Help Pleeezzzz! I think I've been staring at this too long. SyntaxError: positional argument follows keyword argument

Build a Social Network with Flask course: video Post Model

Snapshot of my Workspace

When I try running app.py, the console keeps returning:

Traceback (most recent call last):
    File "app.py", line 6, in <module>
        import forms
    File "/home/treehouse/workspace/forms.py", line 6, in <module>
        from models import User
    File "/home/treehouse/workspace/models.py", line 45
        rel_model-'posts'
        ^
SyntaxError: positional argument follows keyword argument

Any help would be much appreciated!

You can't share a direct URL to your workspace, it's temporary and only exists while you are using it.
But you can use the snapshot function in the workspace and provide the link to that.

Thanks Steven Parker for explaining! I have now provided a link to a snapshot. :)

I think you want to change:

related_name-'posts'

to:

related_name='posts'

Also, a little later you say:

order_by - ('-timestamp',)

Again, I think you want to change the dash to an equals sign:

order_by = ('-timestamp',)

Thank you, adrian miranda! That fixed my issue. :) Thanks again!

It is not clear what you are trying to do, so I will have to guess. Apologies if I guess wrong

Your code says:

user = ForeignKeyField(
        model=User,
        rel_model-'posts'
    )

ForeignKeyField is apparently a function or method call. The first argument you give it is in the form model=User. That means to tell the ForeignKeyField call you have an argument called model, and it will then look for a variable/function/whatever named User to hand in. I'm not sure that is what you intended. Perhaps you meant to call it with Model which was the argument given to the surrounding function?

Your second argument is rel_model-'posts' this appears to mean, a variable called rel_model from which you are going to subtract a string called 'posts' Is that really what you intended? If you wanted to stick a couple strings together, you could a plus sign, like rel_model + '-posts'. But it's not clear what you are intending.

The reason it is complaining is that the first argument to ForeignKeyField is in the form name=value. This is called a keyword argument, because you gave it a keyword, in this case model. Again I'm not quite sure that is what you intended. But if it was, you cannot follow it with an argument that does not have a keyword.

Hi adrian miranda! Thanks for your time. Sorry to throw off your answer, but I was careless. :( When I made some changes to my code while trying to fix my problem, I changed some names and forgot to correct them before I took the screenshot. Really sorry. I have now corrected my screenshot and the code you referenced reads like below:

    user = ForeignKeyField(
        rel_model=User,
        related_name-'posts'
    )

I don't know how much this affects your answer, and how many of your questions still apply.

I am still receiving the same error and any more help you'd be willing to offer would be appreciated. Thanks again! :)
