Inlines weird behavior with django-grappelli integration #232
Description
I'm running into some weird behavior when trying to run/integrate a multiple layer nested admin with grappelli.
Here's the original issue opened on django-grappelli
here's the dummy models I have. Nothing too fancy, pretty straightforward nested models. Note that the Article has two foreign key referencing it. One from the image and one from the paragraph models.
class TableOfContents(models.Model):
title_tableofcontents = models.TextField()
class TocSection(models.Model):
title_tocsection = models.TextField()
table_of_content = models.ForeignKey(TableOfContents, on_delete=models.CASCADE)
class TocArticle(models.Model):
title_tocarticle = models.TextField()
section = models.ForeignKey(TocSection, on_delete=models.CASCADE)
class TocParagraph(models.Model):
title_tocparagraph = models.TextField()
article = models.ForeignKey(TocArticle, on_delete=models.CASCADE)
class TocImage(models.Model):
title_tocimage = models.TextField()
article = models.ForeignKey(TocArticle, on_delete=models.CASCADE)
Here's how my admin looks without trying to rearrange the nested inlines. Also nothing too fancy here pretty straightforward, just note that article is already an inline of sections (which is an inline of table of content)
class TocParagraphInline(NestedStackedInline):
model = models.TocParagraph
class TocImageInline(NestedStackedInline):
model = models.TocImage
class TocArticleInline(NestedStackedInline):
model = models.TocArticle
inlines = [TocParagraphInline, TocImageInline]
fieldsets = [
(
"Image Data",
{
"fields": [],
# "classes": [
# "placeholder tocsection_set-1-tocarticle_set-0-tocimage_set-group"
# ],
},
),
(
"Paragraph Data",
{
"fields": [],
# "classes": [
# "placeholder tocsection_set-1-tocarticle_set-0-tocparagraph_set-group"
# ],
},
),
(
"Article Data",
{"fields": ["title_tocarticle"]},
),
]
class TocSectionInline(NestedStackedInline):
model = models.TocSection
inlines = [TocArticleInline]
class TableOfContentsAdmin(NestedModelAdmin):
inlines = [TocSectionInline]
admin.site.register(models.TableOfContents, TableOfContentsAdmin)
Here's how things look on the admin UI
Now as you might have guessed, my goal is to rearrange the inlines image and paragraph under the designated fieldsets for each category. When uncommentting the classes to try to rearrange them some weird behavior happen. here's a screenshot
As you can see the sections have been rearranged correctly but as a consequence:
- The title of the fieldset, here
Image DataandParagraph Datahave disappeared. - The blue tabs to un-collapse the inlines does not work on preloaded inlines
2.1 If I add a new article the un-collapsing works but the title of the fieldset mentioned in 1) is not present either. - The add Image and Paragraph buttons also stop working when the inlines are moved.
I see that django-nested-admin has good intention in supporting grappelli. Would appreciate any help or directions, happy to contribute if I can help!
