修改管理模子,代码如下:
- class CsvImportForm(forms.Form):
- csv_file = forms.FileField()
- @admin.register(Hero)
- class HeroAdmin(admin.ModelAdmin, ExportCsvMixin):
- ...
- change_list_template = "entities/heroes_changelist.html"
- def get_urls(self):
- urls = super().get_urls()
- my_urls = [
- ...
- path('import-csv/', self.import_csv),
- ]
- return my_urls + urls
- def import_csv(self, request):
- if request.method == "POST":
- csv_file = request.FILES["csv_file"]
- reader = csv.reader(csv_file)
- # Create Hero objects from passed in data
- # ...
- self.message_user(request, "Your csv file has been imported")
- return redirect("..")
- form = CsvImportForm()
- payload = {"form": form}
- return render(
- request, "admin/csv_form.html", payload
- )
复制代码 创建模板文件templates/entities/heroes_changelist.html
- {% extends 'admin/change_list.html' %}
- {% block object-tools %}
- <a href="import-csv/">Import CSV</a>
- <br />
- {{ block.super }}
- {% endblock %}
复制代码 创建模板文件templates/admin/csv_form.html
- {% extends 'admin/base.html' %}
- {% block content %}
- <div>
- <form action="." method="POST" enctype="multipart/form-data">
- {{ form.as_p }}
- {% csrf_token %}
- <button type="submit">Upload CSV</button>
- </form>
- </div>
- <br />
- {% endblock %}
复制代码 显示效果如下:
