Hi all
A while ago I had a problem as described below. I found the solution so am
posting it
here in case others have the same prob in future.
The "Error: variable not passed into template?" was appearing where the
headings for
the table showing the contents of the Data model should have been - but there
were no
headings. So it was the headings i.e. the field names of the model that were
not
being passed into the template.
(The text of "Error: variable not passed into template?" comes from
TEMPLATE_STRING_IF_INVALID in my settings file.)
Notice in my Class I had experiment_id and node_id, particularly they have _id
at the
end. This is what caused the problem. If instead of this:
Class Admin:
pass
I have:
Class Admin:
list_display('id', 'experiment_id', 'node_id', 'content')
Then in admin the Data table show the correct headings and there is no errors.
ID Experiment id Node id Content
Hence it appears that in a model that if one has fields with _id in their name
there
are problems.
