Django formset with crispy - 提交按钮不提交

Question

我正在使用带有 crispy 的 FormSet，每行只有一个提交按钮，但是点击提交目前不会更新记录。我已经搜索并找到了一些类似的答案，这些答案表明提交不在表单内，但我的是。另外缺少一个表单操作，但是 none 我的其他脆皮表单有操作并且它们可以正常工作。

从下面的代码中可以看出是否还有其他原因导致记录无法保存？

forms.py

class ChangeGroupForm(FormHelper):
    def __init__(self, *args, **kwargs):
        super(ChangeGroupForm, self).__init__(*args, **kwargs)
        self.form_method = 'post'
        self.css_class = 'form-inline'
        self.form_id = 'changegroup_form'
        self.form_show_labels = False 
        self.layout = Layout(
            Div(
                Div(                          
                    Div(
                        Field('group', placeholder='Group', css_class="form-control mb-2 mr-sm-2"),
                    css_class='col-lg-3'
                    ),    
                    Div(
                        Field('gps', placeholder='gps coords', css_class="form-control mb-2 mr-sm-2"),
                    css_class='col-lg-8'
                    ), 
                    Div(
                        HTML("""<input type="submit" name="submit" value="Save" class="btn btn-primary mt-1"/>"""),
                    css_class='col-lg-1'
                    ),               
                css_class='row'
                ),
            )
        )
        self.render_required_fields = True

您需要将这样的东西附加到您的视图中

def db_change_groups(request):
    ....
    if request.method == "POST":
        form = ChangeGroupForm(request.POST)
        if form.is_valid():
            # Access cleaned data with
            group = form.cleaned_data['group']
            # Then you can save this to a model.

            # return success template or something
        else:
            # Check for errors.

如果您使用 ModelForm 而不是 FormHelper 创建表单，则可以使用 form.save() 自动将其保存到模型中。
