File_column and fixtures

Rails

Hi *,
I have a problem in creating fixtures for models with file_column
columns.

superman:

This generates:

  1. Error:

What I don’t understand is why fixtures work for certain models and
doesn’t work for others … I wrote unit tests for the Image model,
but Rails complains about tests of another model that just loads
those fixtures …

Someone has an idea ?

From the looks of the error message, it looks like a validation is
failing. Does
/Users/ngw/zooppa/config/…/public/assets/image/image/1/superman.png
exist?

No, at all.
But all the other fixtures work, I thought I could fake it.
I also have no idea on how to upload a file inside fixtures, so …
You use file_column ? How do you write fixtures ?

TIA,

Fixtures use your model to load the data, so in order to use a fixture,
the data supplied must pass any validation you have in your model. One
possibility would be to leave that column empty in your fixture and
dynamically populate it in a test / helper. I don’t actually use that
plugin, so I can’t really help there, but it seems you may need to dig
into how it works a bit and glue something together. Does that plugin
come with a test helper that you can use? Fixtures are processed as erb
files so if there is a helper you can use to load data into that field,
you could use it like:

image_column: <%= helper_method -%>

Hope this helps to at least steer you in the proper direction.
