CodePudding user response：

user_id = User.objects.get(id=request.user.pk)

Get the object and pass it in to create a query it will work,Because ForeignKey accept object intend of id or any value

CodePudding user response：

You'd need to change your likefilter as currently you're trying to retrieve a LikePost with post_id and user_id attributes. You should have something like:

like_filter = LikePost.objects.filter(post_id=post_id,user_id=user_id).first()

And I may be wrong but it seems like your user_id contains the username value of your user instead of its id, so you could also change that to:

user_id = request.user.id

CodePudding user response：

user_id = request.user.pk
like_filter = LikePost.objects.filter(post_id=post_id, pk=user_id).first()

try this way
