00:00:01

will create dynamic pages to

00:00:03

display each individual article

00:00:05

but first I want to recommend the site and

00:00:08

these Prager dot com on this site you

00:00:10

will find the homework code and a lot of

00:00:12

other useful information the link to

00:00:14

this lesson on the site will be in the description of

00:00:16

this video

00:00:17

during this lesson we will create a

00:00:19

page that will be available at the

00:00:21

following url address for example newsflash

00:00:24

and then dynamic parameters for example

00:00:26

one two three four and so on and

00:00:29

depending on these dynamic

00:00:31

parameters and on this page we will

00:00:33

show information either about the first

00:00:35

article either about the second article or about the

00:00:37

third article and so on, that is, we

00:00:40

will have only one page,

00:00:42

we will have this constantly

00:00:44

changing legal address and depending on

00:00:46

what parameter will be

00:00:48

substituted here, what number will be

00:00:50

substituted here depending on this on this

00:00:52

page we will show this or that

00:00:54

article,

00:00:55

well, let’s implement this now

00:00:57

before we start writing it all out with you,

00:00:59

I want to draw your attention to the

00:01:00

fact that earlier I said that in django

00:01:03

there are two ways to manipulate

00:01:06

records that are in the database the

00:01:08

first way is when we can

00:01:10

simply create our own function and write something like this in it, something like this,

00:01:14

and the second way is that we can create

00:01:17

classes based on the predefined

00:01:20

classes that are in django, and

00:01:22

we have already discussed the first method

00:01:24

yes, we have already created our own function and

00:01:26

now it’s time to consider the second

00:01:28

method, that is, we will create a class here and

00:01:30

it will inherit everything from the

00:01:33

built-in django classes and inside

00:01:35

this class we will also write

00:01:38

some characteristics and thereby

00:01:40

create this dynamic page to

00:01:42

display each a separate article, so I

00:01:45

suggest let’s initially

00:01:48

just create a class here inside the views policy, then we’ll learn to

00:01:50

track the url address, but then we’ll

00:01:52

create the html template itself. To

00:01:55

create a class, we initially need

00:01:57

to import the built-in class, so we’ll go from Jung,

00:02:00

then from views, then from the folder generic

00:02:04

we import a class

00:02:06

called detailsview, just

00:02:09

based on this class you can create a

00:02:11

cat page that

00:02:12

will constantly change

00:02:13

depending on the parameter that will

00:02:16

tell the address and we are doing exactly this with

00:02:19

you now and let’s do it

00:02:21

somewhere here we are Let’s just write down the

00:02:23

creation of a new class, this will be

00:02:25

our new class, the class itself can be called

00:02:28

whatever you want, for example, let’s use the

00:02:30

sound as news detail view, its name

00:02:33

can be anything, the main thing is that you

00:02:34

must indicate that it inherits everything from the

00:02:36

detail view class,

00:02:38

here inside the class we with you we

00:02:41

simply indicate some

00:02:42

characteristics, firstly, I must

00:02:44

say that we will work with a

00:02:46

model called articles,

00:02:48

so here I indicate Olya’s model and

00:02:50

indicate that we are working specifically with the

00:02:52

articles model,

00:02:53

then we also need to specify the

00:02:54

template name variable here and in it we

00:02:56

simply indicate which template will

00:02:58

process the page here, as it were, I

00:03:00

will have a template that will be

00:03:02

called detailsview a little later we will

00:03:05

create this template ourselves, and

00:03:08

additionally I will also indicate the

00:03:10

context variable object name here, this is

00:03:12

just, well, this is just essentially like

00:03:14

the name of the key by which we will

00:03:16

transfer the very specific record

00:03:19

inside the template, well, you can come

00:03:21

up with a name absolutely anything I want, for

00:03:23

example, let’s indicate the name as a post,

00:03:25

or maybe let’s do better as an

00:03:27

article, it will be more logical and probably

00:03:29

the name, that is, it’s just like a key

00:03:31

for which we are passing a specific

00:03:34

object inside the template, but

00:03:36

we’ll get to know all of this a little later. Now let’s

00:03:38

go to the urals policy. pine and here we

00:03:41

will create a new tracking url address,

00:03:44

what needs to be done here,

00:03:46

firstly, you and I must track a

00:03:48

url address that will begin

00:03:49

with the word news and here we specifically in

00:03:53

this file do not need to register this word news

00:03:55

here we are, as it were, registered that

00:03:57

the part that already comes after this word,

00:03:59

well, here we can’t just write

00:04:02

that we will cut off Yuri’s

00:04:03

address, for example 123 or something like that,

00:04:06

we need to indicate that we are tracking

00:04:08

a certain dynamic parameter, and to

00:04:10

indicate that we will cut off a dynamic

00:04:12

parameter we must open and close

00:04:14

angle brackets inside them we indicate

00:04:16

that we are tracking a dynamic parameter

00:04:18

which is an integer for us and

00:04:20

then, separated by a colon, we must name

00:04:22

this itself in pairs,

00:04:24

i.e. let's use it on sounds and those are

00:04:26

the primaries and well, you will run the primary key,

00:04:29

this is quite logical and the normal name

00:04:31

will be for this parameter, here is an important

00:04:33

point, do not put any spaces, otherwise there

00:04:35

will be errors, nothing will work,

00:04:37

so we just indicated that we are

00:04:39

tracking how the url -address that

00:04:41

should start with the word news here we

00:04:44

just didn’t register it with you because

00:04:45

in the main file and duralumin cm it’s already

00:04:47

kind of written down, and then we just

00:04:49

wrote here that we’ll cut off some

00:04:50

dynamic parameters 12 and so on,

00:04:53

something like this in this spirit, and now we

00:04:56

need to say the following: if we

00:04:59

go to such a url address,

00:05:01

then we must call this time

00:05:03

not any method, not any

00:05:05

function, but we must call the class,

00:05:07

which we call news dll

00:05:09

view, in order to indicate this to us, we also

00:05:12

refer to and kill the file, and here we

00:05:14

simply refer to cnews d t l the

00:05:17

only difference when calling a function and

00:05:19

calling a class is that here at the end

00:05:21

we still need to refer to a

00:05:23

method

00:05:24

called s- view if we

00:05:26

haven’t done this here, see, and don’t turn

00:05:29

to the method in the fall, then we will

00:05:30

get an error, and also since

00:05:33

we are already working with and named me

00:05:35

Yuri addresses, then let us also

00:05:37

indicate here some certain name and the name will be like

00:05:40

news dtl for example this is the name for

00:05:43

this Yuri, we will

00:05:44

indicate the addresses here, now we

00:05:46

need to create a new template,

00:05:49

let's just copy the

00:05:51

name and template folders here,

00:05:53

we will just create a new template and a new

00:05:56

file for the family. eat they say, well, so we

00:05:58

created it inside this file,

00:06:00

let's paste all this code that

00:06:02

we had in the news home file,

00:06:03

we just copy it from there and

00:06:05

paste it here and let's maybe you'll

00:06:08

delete the entire lower part here for now and

00:06:10

just write it down a new code, see

00:06:13

the h1 tag, I want to see not just a certain

00:06:16

post, but I want to see the title of this

00:06:18

article to which we have switched, in order for me to

00:06:20

do this, I need to

00:06:22

refer to the article object here, this is

00:06:25

the name we put here before m, that is, we ourselves

00:06:27

indicated it here in the class we

00:06:28

indicated that we are passing an object by the

00:06:30

name article

00:06:31

here I simply refer to this as a

00:06:33

title and just like before

00:06:35

through a dot I just

00:06:37

6 to the desired pain which I want to display

00:06:39

I want to display the title

00:06:41

but here I want to display the title of

00:06:42

the article here so I turn to the article and

00:06:44

turn to the title,

00:06:46

and it will be displayed here. I would also

00:06:48

like to display the full text of the article.

00:06:50

For this, I also write down what when

00:06:52

turning to the article and here and here I already

00:06:55

display, for example, the full text, and

00:06:57

in addition, perhaps by the way, let us do

00:06:59

this let's do it a little higher, that is, right here

00:07:02

at the top, I would also like to display the date of publication of the

00:07:05

article itself, mark the profession, cut off

00:07:07

and display simply d, that is, the date

00:07:10

of publication of the article,

00:07:11

let's now

00:07:13

see what we got, we'll just

00:07:15

go to the URL for now, for example

00:07:17

news is one and we can notice that everything

00:07:20

was processed correctly for us, that is, we

00:07:22

are displayed here the title of the article

00:07:24

here we are displayed yes, well, here we

00:07:27

are shown as if the full text of the article itself,

00:07:29

that is, with the help of classes you can

00:07:32

actually do even more in a simple

00:07:34

format to implement

00:07:36

the functionality we need, that is, here we

00:07:38

were still thinking about this

00:07:41

sql query itself, well, we were kind of thinking

00:07:43

about what methods should be

00:07:45

used here, but here everyone quite

00:07:47

simply indicated a certain model,

00:07:49

it seemed like a template and indicated using

00:07:52

using what kind of name do we

00:07:54

transfer the data inside this

00:07:56

template itself and there is no need to register anything else here, the

00:07:59

same predefined classes

00:08:01

exist and to display all records,

00:08:04

for example, there is a class

00:08:05

called something like seven and on its

00:08:07

basis you can, well, you can practically

00:08:09

register the same thing just point out that we

00:08:11

are using list view and based on the family

00:08:14

we will create a template inside of

00:08:16

which we will display all the records

00:08:18

from a certain table and there are many such

00:08:20

pre-installed classes, for

00:08:22

now let’s

00:08:23

just focus on the dtl view

00:08:26

now next to each article we will

00:08:28

additionally let’s display a

00:08:30

button when clicked on which we will

00:08:32

go to the URL address for example news 1

00:08:35

news2 news 3 and so on, that is, it

00:08:37

will be a button for more details and

00:08:39

reading of an article, and to

00:08:42

do this we need to go to the

00:08:43

news template here under the output with the announcement,

00:08:47

let's create a new link while we wo

00:08:49

n't enter the legal address,

00:08:51

let's just add here the

00:08:53

bottom loaf warning style, that is,

00:08:55

this is the style from bootstrap and here it will be

00:08:57

written, for example, read in more detail

00:09:00

for example and that's all, and now you need to specify

00:09:03

Yuri abyss himself here we are the url we will

00:09:06

indicate the address using named links,

00:09:08

that is, we are addressing you real and

00:09:10

then we need to address

00:09:12

this url address, which is called

00:09:13

news dtl, so let’s give it here

00:09:16

as a name and write it down, but

00:09:18

news detail is the url address that

00:09:21

also accepts certain dynamic

00:09:23

parameters and this dynamic parameter

00:09:25

we need to pass it here,

00:09:27

in order to pass a dynamic parameter

00:09:29

simply separated by a space, we indicate here the

00:09:32

value that we will

00:09:34

pass, I can simply indicate

00:09:35

the number two here and we will always have

00:09:37

dynamic parameters substituted, this is this, this is

00:09:40

this number, but this is not exactly

00:09:42

what I need, I need to pass on the

00:09:44

ID of each specific entry, and

00:09:46

to do this I turn to lm in the same

00:09:49

way as here we displayed

00:09:51

the title or announcement, also I turn to

00:09:53

lm and turn to such a pain as ID,

00:09:56

here it is in the migration files, you

00:09:59

can even open their migration file, we have

00:10:00

always created a separate

00:10:02

field here called ID,

00:10:04

this is an automatically created field and it

00:10:07

essentially represents a certain

00:10:08

serial number of each specific

00:10:10

record and it is this field we will

00:10:13

pass as a parameter to the legal address, that

00:10:16

is, for example, yes, for the first article

00:10:18

it will be the value 1 for the 2nd article it

00:10:20

will be the value 2, so then if we

00:10:22

now save this and update

00:10:24

the page, then we have buttons, when you

00:10:26

click on the button we go to well so

00:10:29

initially, for example, for our last

00:10:31

article, I go to the Yuri address news 4

00:10:34

and here it is displayed as if this is

00:10:35

my article, let’s also

00:10:38

go for example to this article and we

00:10:40

go to the url address news 3 and here it

00:10:42

is displayed as if the third is here is

00:10:45

the article, all I propose to do in

00:10:47

this video is let’s change the

00:10:49

python for each of these pages

00:10:52

because now where we haven’t gone to the title, it’s the

00:10:54

same everywhere here, it’s not

00:10:56

very

00:10:57

cool, well, in fact,

00:10:59

we don’t have to change the title you will need to

00:11:01

perform any additional actions,

00:11:04

all we need to do is this

00:11:06

here you will forget,

00:11:07

we need to transfer the title in the

00:11:10

article format.

00:11:12

python, in general, all this

00:11:14

was a very, very easy solution, well, where have

00:11:16

n’t we gone now? 8 languages are written here that are

00:11:19

suitable for you, here we have, I’ll

00:11:21

forget about another article, then this

00:11:22

Chinese thing will be different, but in general, then

00:11:24

now these pages look pretty

00:11:26

good,

00:11:27

of course, here you can still work

00:11:28

on the styles, but the main thing is that all the

00:11:30

functional part of us is completely

00:11:32

recreated and you can already work with the styles, you

00:11:34

can simply add them at any

00:11:36

appropriate moment, well, that’s

00:11:38

all for me, so subscribe to the channel and

00:11:40

join VKontakte group and also

00:11:42
