Using a request object

If you want to access the request object for the admin, doing actions like create/update/delete you can override the specific ModelView methods.

These methods include:

• insert_model(request, data)
• update_model(request, pk, data)
• delete_model(request, pk)

A common use case is to access the request.user and store that in create/update model:

class User(Base):
    __tablename__ = "user"

    id = mapped_column(Integer, primary_key=True)
    name = mapped_column(String)


class Post(Base):
    __tablename__ = "post"

    id = mapped_column(Integer, primary_key=True)
    text = mapped_column(String)
    author = relationship("User")
    author_id = mapped_column(Integer, ForeignKey("user.id"), index=True)

And whenever a new Post is created we want to store the current admin user creating it. This can be done by overriding the insert_model method:

class PostAdmin(ModelView, model=Post):
    async def insert_model(self, request, data):
        data["author_id"] = request.user.id
        return await super().insert_model(request, data)

Here we've set the current request.user.id into the dictionary of data which will create the Post.

The same thing can be done to control update and delete actions with the methods mentioned above.
