我有以下模型表单，必须在其中添加一个隐藏字段。

该表单仅显示隐藏的表单字段，并且不显示“名称”字符字段。当我将字段“ id_sel_comp”标记为未隐藏时，将显示所有字段。这有什么问题？ 表单使用以下模板呈现在模板中：
class AddEditGroupForm(forms.ModelForm):
id_sel_comp = forms.CharField(
label='selected company',
initial=0,
required=True,
widget=forms.HiddenInput(attrs={'id': 'id_sel_comp'})
)
class Meta:
model = Group
fields = ('name', 'id_sel_comp')
def __init__(self, *args, **kwargs):
super(AddEditGroupForm, self).__init__(*args, **kwargs)
self.fields['name'].widget.attrs.update({'class': 'form-control m-input form-control-sm'})
def as_two_col_layout(self):
return self._html_output(
normal_row='<div class="form-group m-form__group row"><label class="col-sm-3 col-form-label">%(label)s</label><div class="col-sm-9">%(field)s%(help_text)s</div></div>',
error_row='%s',
row_ender='',
help_text_html=' <span class="m-form__help">%s</span>',
errors_on_separate_row=True)

您没有正确指定program Project2;
{$APPTYPE CONSOLE}
{$R *.res}
uses
Windows,
Classes,
SysUtils,
Magnification;
type
THostWNDThread = class(TThread)
private
class function WindowProc(hwnd: HWND; uMsg: UINT; wParam: WPARAM; lParam: LPARAM): LRESULT; stdcall; static;

srcheader: MAGIMAGEHEADER; destdata: Pointer; destheader: MAGIMAGEHEADER;
unclipped: TRect; clipped: TRect; dirty: HRGN): BOOL; stdcall; static;

procedure Execute; override;
public
end;
procedure THostWNDThread.Execute;
var

finally

。您当前将其设置为“”，这与您指定的row_ender不正确。您的normal_row是row_ender。这样您的</div></div>就变成了，
as_two_col_layout希望这会有所帮助！
