12,964 PointsHelp 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
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!

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',)

13,561 PointsIt 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.

12,964 PointsHi 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! :)

But you can use the snapshot function in the workspace and provide the link to that.
