dynamic FilePathField question

Question

I have a model where the location of pdf directory I\'m pointing to with my FilePathField is based on the \"client\" and \"job_number\" fields.

class CCEntry         


        

Answer 1

Anyone interested in extending FilePathField to include this feature?

I'd love to see this extension!

Just for the record, this is the solution that worked for me (django 1.3):

    # models.py
    class Analysis(models.Model):
        run = models.ForeignKey(SampleRun)
        # Directory name depends on the foreign key 
        # (directory was created outside Django and gets filled by a script)
        bam_file = models.FilePathField(max_length=500, blank=True, null=True)  

    # admin.py
    class CustomAnalysisModelForm(forms.ModelForm):
        class Meta:
            model = Analysis
        def __init__(self, *args, **kwargs):
            super(CustomAnalysisModelForm, self).__init__(*args, **kwargs)
            # This is an update
            if self.instance.id:
                # set dynamic path
                mypath = settings.DATA_PATH + self.instance.run.sample.name
                self.fields['bam_file'] = forms.FilePathField(path=mypath, match=".*bam$", recursive=True)

    class AnalysisAdmin(admin.ModelAdmin):
        form = CustomAnalysisModelForm

Hope this helps somebody out there.
