You got lucky, you might have pasted just enough of the traceback to receive some help.

Check the data you have in your database, look like there is no object Project with an id=1.

Hi,

I think his point is that no file change will resolve this. :-)

In the file "brickly/framework/middleware.py" you are searching for a Project with the database ID 1 - and it doesn't exist. The middleware apparantly needs a Project to function. 

So you can either add a project to your database, or you can remove that line in the middleware file - either would solve THIS issue - however removing the line, will probably add other problems instead.

Regards,

Andréas

Hi,

Previous error solve and thanks for that.

now i am getting new error of ValidationError Please see below screen shot.

Please let me know of what is the problem now.

[Camilo Torres]

Hi
1) How did you solved the first issue? You should be supposed to solve it by adding a row to a database table (the one related to your Project model) with id=1.
2) You have not pasted enough information for your ValidationError issue, please don't paste screen shots (at least, not only a screen shot). Please paste the entire stack trace you get in the terminal running the server. You may also consider pasting relevant code you think is related to the error, though someone can ask for the code or configuration after looking at the entire stack trace.

At this point, I usually start putting a lot of print statement, both in my code and in library. That's one of the advantages of working in a virtualenv.

My gut feeling is that on of the fields of Project is causing the validation error. If I could read the code of the Project model, maybe I could make a better guess. Maybe not.

You should try to find what value of what object/attribute is causing the error. I use print for that job. A good debugger could do the trick too.

I would search the function doing the redirection and look at what information it use to make that redirection.

Either it is redirecting to a wrong url or something have gone wrong when installing the brickly application.

Hi,
I agree with Ludovic in "your application may be badly installed". But it is very hard to tell what is going wrong without actually knowing what your app should show (what view function) for URL path /brickly/home
I cannot tell you what view is that without knowing about your code nor your business rules for that page.
You have to ask the original developers what view should show there, and try to writhe the url conf for that.
