WTForms getting the errors

由 ＊爱你＆永不变心＊ 提交于 2019-12-03 01:57:12
Currently in WTForms to access errors you have to loop through field errors like so: for error in form.username.errors: print error Since I'm building a rest application which uses no form views, I'm forced to check through all form fields in order to find where the error lies. Is there a way I could do something like: for fieldName, errorMessage in form.errors: ...do something The actual form object has an errors attribute that contains the field names and their errors in a dictionary. So you could do: for fieldName, errorMessages in form.errors.items(): for err in errorMessages: # do

Disabled field is considered for validation in WTForms and Flask

由 拜拜、爱过 提交于 2019-12-02 19:33:45
I have some fields in page disabled as for example:(using jinja2 templating system) <html> <body> <form action="" method=POST> {{ form.name(disabled=True) }} {{ form.title }} -- submit button -- </form> </body> </html> Field is disabled in the form as expected. In my views.py: On doing validate_on_submit() on form submit, it fails with validation error on 'name' field which is disabled. I was hoping that validation ignores disabled field. Is it the right behaviour? If so, can you please let know how to handle such a case? Updated: class TeamForm(wtf.Form): name = wtf.TextField("Team Name",

Flask-SQLAlchemy: How to conditionally insert or update a row

由 强颜欢笑 提交于 2019-12-02 17:37:30
My application uses a combination of Flask, Flask-SQLAlchemy, Flask-WTF and Jinja2. In its current incarnation, I have a settings table. The table will only have one record with one field. Initially the table contains zero records. What I want to achieve is: Given that no entries exist in db, then show empty form ready for user input Given that an entry exist, show the entry, and if the user changes the value, then update the rec in db. Here is my code: models.py class Provider(db.Model): id = db.Column(db.Integer, primary_key = True) rssfeed = db.Column(db.String(120), unique = True) def _

WTForms: IntegerField skips coercion on a string value

由 南楼画角 提交于 2019-12-02 08:08:43
问题 I have a Form instance with a single IntegerField . The IntegerField renders to HTML as an <input> with type="text" and data gets POSTed back from an HTML form as a text string. However the form will not validate if the posted data has a string value for the IntegerField (passed in via a dict in the data parameter). Here's a toy example: from wtforms import validators, Form, IntegerField class TestForm(Form): num = IntegerField('How Many?', [validators.NumberRange(min=1, max=100)]) test_form1
