One to One Relationships in Flask-SQLAlchemy

One to One relationships are a special case that you may have in your project. In this video, I talk about how to create them in Flask-SQLAlchemy.

I know this is old but this still is the only helpful tutorial i found. Most of the videos Ive watched doesn't deal with relationships. Thank you. Been looking for this for the last couple days.

My wife asked me, why I quitted django, I told her that there is no more django content from Pretty Printed (with tears in my eyes)

I am using Flask for an educational project. Your videos are helping a lot.
Great work, thanks!

Hi Anthony
Thanks for your videos.
I have a question about the backref, you chose
parent as the name. Does this mean that the column
in the child class needs to be named parent_id ?
or are these 2 resources completely uncorrelated ?
Thanks a lot.

@prettyprint... do you have a tutorial on how to insert data into the parent and child tables with a little bit realistic project? kind regards

[bogdanvelica]

Any idea who you can get the data in jinja2 tempalte from a child template? Usually i used (from your tutorials) current_user.firstname when the firstname was in the User table, but I we move that to UserDetails table, how do we get that? Thank you

How do we add a Column to Parent that shows all of his children?

i am getting out of context error dont know why even though i followed the same steps

[farzinashouri]

In the line child = db.relationship(....) what is child? I mean is it table name? or record? or just an arbitrary name?

[noobdaaviacao]

I'm in doubt about it. How is the structure of the code to identify the user who made a post? Is it the route or the form? I'm stuck in this car in the flask is it helping me?

Thank you for this video! Can the parent have the one-to-one relationship with the child, but also have a one-to-many relationship with another table?

how to create a parent related to the first child with no parent anymore?

[alexd]

using 'Child' and 'Parent' in this context doesn't make sense, because a child/parent relation is usually M2M. A better example could be for example Student - student_IDCard
