Question

我正在开发一个Python-Flask Web应用程序，它应该可以作为政治家的维基百科。当我创建一个新的政治家时，它被默认为草稿，可以被更高级别的成员接受。因此，当我创建政治家页面时，它被检查作为草稿，当管理员接受该草稿时，草稿值将转到 false 。我想知道如何根据属性草稿的列值勾选/取消勾选复选框，这是布尔（True / False）。然后我想根据表单结果更改它。这是一个编辑功能，你会看到：

这是我的政治家表格，我用来编辑的表格：

class PoliticForm(FlaskForm):
  publicName = StringField('Public Name', validators=[DataRequired("Please enter politician public name.")])
  completeName = StringField('Complete Name', validators=[DataRequired("Please enter politician complete name.")])
  startDate = DateField('Start Date', format='%m-%d-%Y', validators=[DataRequired("Please enter the politician start Date.")])
  endDate = DateField('End Date', format='%m-%d-%Y', validators=(validators.Optional(),))
  draft = RadioField('Draft', choices=[(True,'Yes'),(False,'No')], )
  submit = SubmitField('Add Politician', validators=(validators.Optional(),))

我想检查 HTML Jinja2 视图中的草稿行，即：

<div class="form-group">
                        <label for="draft">Draft</label>
                        <input type="checkbox" name="draft" class="form-control" id="email" value="{{politician.draft}}">
                    </div>

我是否需要使用已检查参数？如何选中 True 并取消选中 False ，然后将该更改发送给我的控制器？

政治家/ views.py / edit_politician

@politicians_blueprint.route("/edit_politician/<idPol>", methods=["POST", "GET"])
@login_required
def edit_politician(idPol=1):
  form = PoliticForm()
  politician = Politic.query.filter_by(idPolitician=idPol).first()
  if request.method == "POST":
    politician.publicName = request.form['publicName']
    politician.completeName = request.form['completeName']
    politician.draft = request.form['draft']
    if request.form.get('date') != 'None':
      politician.startDate = datetime.datetime.strptime(request.form.get('date'), '%m/%d/%Y').strftime('%Y-%m-%d')
      print politician.startDate
    if request.form.get('date2') != 'None':
      politician.endDate = datetime.datetime.strptime(request.form.get('date2'), '%m/%d/%Y').strftime('%Y-%m-%d')
      print politician.endDate
    db.session.commit()
    return redirect(url_for('home.home'))
  elif request.method == "GET":
    print politician.startDate
    if politician.startDate is not None:
      dateStart = politician.startDate.strftime("%Y-%m-%d")
      politician.startDate = datetime.datetime.strptime(dateStart, '%Y-%m-%d').strftime('%m/%d/%Y')
    if politician.endDate is not None:
      dateEnd = politician.endDate.strftime("%Y-%m-%d")
      politician.endDate = datetime.datetime.strptime(dateEnd, '%Y-%m-%d').strftime('%m/%d/%Y')

    return render_template("editPolitician.html", politician=politician)

有什么想法吗？我真的很挣扎......

Answer 1

您可以尝试类似

的内容

<input type="checkbox" name="draft" class="form-control" id="email" {% if politician.draft %}checked="checked"{% endif %}>

或者通过jQuery修改复选框的状态（如果你使用它）

<script>
  {% if politician.draft %}
    $('input[name="draft"]').prop('checked', true);
  {% endif %}
</script>

从数据库导入复选框值
