Do you have free copy for it ??

Nope, you have to buy it

Why, when I am working on a project, I turn off the laptop, and then continue later, the project does not respond to the modifications of the css codes

If it's bootstrap, it will work when you connect to the Internet or after clearing cache.

Is it the console in the browser or something else?

I don't get.

How do I clean the cache

Why do we need lookup_url_kwarg anyone would like to explain

If you're extending a view that retrieves an object. Basically telling the view to pick the value in the url and use it in your query

You can override the form_valid() method for the CreateView: https://stackoverflow.com/a/33001010 You can try the first option in the answer. The newly created object can be accessed using self.object in there

guys, how do I get an id? i did this: parent=Post.objects.only("id").get(id=self.kwargs["id"]) print(parent)#it gives me the description of the post print(parent.id)#it gives me the id but when I submit it... Cannot assign "UUID('123456789')": "Post.parent" must be a "Post" instance.

can you be more specific by "when I submit it"?

in any case you should be using values() in your query: .filter(id=<your id>).values('id', flat=True)[0]

form.instance.parent=parent.id I want to give post's id to the repost

I'm still not entirely sure what you're trying to do. do you have a foreign key relationship and you're trying to set post as a related model or something?

and the way you're trying to set it is by directly assigning the foreign object's primary key value? is that why you're getting its id?

when managing relations, typically you don't want to work with primary keys directly if you can avoid it. it's better to use something like add(). example. say you've got a model called Post. it has a foreign key field pointing to another model called Content. if you wanted to add a specific Content to a specific Post, this is how you'd do it: post = Post.objects.get(...) content = Content.objects.get(...) # this way post.content = content post.save() # or this way content.posts.add(post)

you could for example do the following: post = Post.objects.get(...) repost = Post.objects.get(...) parent_post = Post.objects.get(...) post.repost = repost post.parent = parent_post post.save()

Hi guys I have a post model like this class Post(models.Model): ........ Likes=models.ManyToManyField(User) I want to add one more field to my query set which is "isliked" Which tell about is logged in user like the post or not Can anyone help

Help a Dev

If the isliked or not property something that can be just for display in a page template, you can use a custom tag for this. Perhaps something like this in template {{ post|isliked:request.user }} And like this in custom_tags.py def isliked(post, user): Check if user is in post.liked
