Hi Shakeel,
It appears that you are referring to:
class Target_File(models.Model):
path = models.FilePathField()
Looking at the documentation for this field type
(https://docs.djangoproject.com/en/2.1/ref/models/fields/), I see:
“FilePathField<https://docs.djangoproject.com/en/2.1/ref/models/fields/#django.db.models.FilePathField>
instances are created in your database as varchar columns with a default max
length of 100 characters. As with other fields, you can change the maximum
length using the
max_length<https://docs.djangoproject.com/en/2.1/ref/models/fields/#django.db.models.CharField.max_length>
argument.”
Clearly 100 characters is very limited, as revealed in your issue. Here are the
choices:
(a) We could go with a TextField redefinition, and have no limit. The problem
is that we lose the associated methods of FIlePathField. I can review the
Toaster code to see if we are actually leveraging those methods, either
directly in the Python code or implicitly in the template code.
(b) Increase the “max_length” to some larger value, for example simply
doubling the default to 200 characters. We could still hit that limit, but
perhaps vanishingly.
Can you give guidance as to what path lengths you are requiring? That will help
give us a real world use case.
Thanks,
David

Subject: [Toaster] Toaster database error
Hi,
I have setup Toaster production instance using Rocko 2.4.2 and it works fine
usually.
Some of our builds have mono libraries and related files (with very long paths
of files to be installed) and for that build I see the following error:
ERROR: (1406, "Data too long for column 'path' at row 1")
And with this error the Toaster fails to show correct status of a command line
build.
I have worked around this by setting Mysql non-strict mode but that doesn't
look like a good solution and may lead to other errors.
Do you think we can change the SQL entry that specifies the length of 'path'
element? What is the limit on this?
Best Regards,
Shakeel
