How to add a variable to a class?

Question

Flask

hello

there is a class

class RestoreView(FlaskView):

    restore =True
    error = ''
    form = RestorePwdForm()

    def get(self):
        return render_template('login.html', form =self.form, restore=self.restore, error =self.error)

    def post(self):


        print(request.form)

        if request.form:
            try:
              a= resetpwd(request.form['email'])
              print(a)
              self.error = 'Ваш новый пароль {0}'.format(a)
            except:
              self.error ="ИДИ ОТСЮДА"
        return redirect(url_for('RestoreView:get'))

in this form, the error raise RuntimeError ('working outside of application context')
RuntimeError: working outside of application context falls out

if you remove variable declarations at the beginning, everything works, why?

Answer 1

transfer form = RestorePwdForm() to the def get method, the error tells you working outside of application context that you are creating an object outside the context.
