问题我希望能够在查看主模板'sheet_form_create.html'时保存我的部分'_dim'，因为某些原因我在发布要保存为'_dim'部分的数据时一直收到此错误。任何帮助将不胜感激。

将views.py中的add_dimension（）更新为此 *这将处理sheet_form键并且还将正确保存：）

当您的form 无效时，您没有向模板发送任何上下文：
dim_form = DimForm(request.POST)
if dim_form.is_valid():
#...
else:
data = 'fail'
return render(request, 'app/sheet_form_create.html')
所以在app/sheet_form_create.html内，没有sheet_form。
所以我猜模板中的sheet_form应该与视图中的dim_form相同？如果那是真的那么你可以：
return render(request, 'app/sheet_form_create.html', {'sheet_form': dim_form})
