I'm building a form editing page using the Formio editor and renderer.
I'd like to make specific form fields mandatory in the form editor. [different than making the field entry mandatory during submission]
There are two roles in the application -
Editor - Modifies the formio definition.
User - Submits the form data.
I'm specifically interested in making several 'meta-data' fields mandatory for the Editor. The Editor should not be able to remove certain fields from the formio component list.
A couple options I'm considering for implementation -
When the form is saved, inspect the form components and ensure the mandatory fields exist, and if they dont, create them.
Set a flag in the UI for specific components so they are 'disabled' and cannot be removed in the formio editor.
Has anyone implemented this?
You seem to be going in the right direction.
You can definitely do (as you suggested):
When the form is saved, inspect the form components and ensure the mandatory fields exist, and if they dont, create them or throw an error
Along with this, you can also extend the form builder and remove the "remove" icon that appears in the builder next to these mandatory components.
To do this,
Add a custom property to all the components, something like "customIsMandatory"
Modify the options.templates of the WebformBuilder to show a different template (one with "remove" icon removed) if the "customIsMandatory" is true for this component.
You can pre-populate these mandatory components in the builder and make sure that this property is set to true for them.

I have a customized form of a customized entity, on my form I have crm annotation (notes), I need to set the notes part as required (according to a rule) how do I do that? when I clicked on the notes field I couldn't see the field name, Is it possible ?
The question reffers to dynamics crm annotation mechanism
We cannot achieve this straight forward, as we know Notes (annotation) is a separate entity which may have many records for a parent entity record. This is not a simple field in form, cannot be accessed in business rule. Instead of showing in subgrid, Platform giving different UI/UX for notes only like Timeline etc.
You can write script to validate/prompt user to create a child note on need basis. But not before creating a parent record itself.
This was already discussed in community, maybe you can have a custom mandatory multiline field to capture notes & rollup to annotation, can handle different scenarios/validations in code.
I have the following problem:
I have a form where a user can opt to toggle a switch (Yes/No).
If they select Yes, I hide a couple of fields on my template (because they will now automatically be calculated).
The catch is that now, a set of different fields are required to not be empty for the successful submission.
The first fields need not be optional after the switch is clicked (since they are merely hidden but still submitted), but the second set of fields must be non-empty.
Is there a simple way to get this dynamic validation behaviour using Symfony's sfValidator classes, or should I simply hack together a solution using jQuery?
This sounds like a perfect case for the Callback constraint that already exists in Symfony. To quote the linked doc:
The purpose of the Callback constraint is to create completely custom validation rules and to assign any validation errors to specific fields on your object. If you're using validation with forms, this means that you can make these custom errors display next to a specific field, instead of simply at the top of your form.
This solves the backend, you still need to watch out for the required attributes of your fields so HTML5 validation can work properly.
I have a custom web control which has two html select field and buttons i use them to make associated and available list box.But in few situations i have to Validate that Associated field must have at least 1 entity. I implemented a client side custom validator to confirm that. and its working great but issue is i am unable to fire Validate at the time List box is made empty it fires when i click save button and similarly when i have moved a few entries in associated List. validation Message is stile there and removes only when i click save button.
So i want to know how can i fire validator when i need using javascript...
To fire a validator from javascript we may use ValidatorValidate(document.getElementById('validator clientID'))

I know with a form, I can get the $valid property to check whether the entire form is valid. Is there a way to get the validity of a form but ignore undirtied fields whose only rule is "required"?
I have a form that has a save button and a next button. This form is part of a series of forms. When the user clicks on save, I want full validation, but if the user clicks on "next", I want it to validate (and alert the user) for all fields except those who have no validation rules on them other than the "required" flag. This is so that I can save a partially completed form without having to alert the user to the missing fields until later (because they will want to save progress on their forms without having to complete them altogether).
Perhaps there's a way to get the fields with a jQuery selector/filter of some kind?
Not sure I completely understand the question and your use case, but it somewhat sounds like you may need to use custom form validation.
http://docs.angularjs.org/guide/forms#custom-validation
(you may need to scroll down a bit when first loading the link)
Basically you may need to add your own custom directive to control the validity of the inputs you have in mind.
Alternatively, and maybe not quite the "Angular" way, you can avoid using the data binding between the fields and model, effectively opting out of Angular validation. Obviously losing the data binding may be a bigger issue for you but you could get at those values with code outside of your Angular stack.
I've built a django model where the required fields change based upon the user's selection on other previous fields. Specifically, it is an event scheduling application where the options change based on choices the user makes.
Some combinations of fields are simply invalid, and I have the model set to check for those and not allow them. However, it is a bit confusing in the UI to figure out the right combinations. I would like the admin UI to help with this by hiding or disabling invalid fields as the user changes other fields.
For example, if the user chooses to make the event repeat weekly, I need to disable (or ideally remove) all of the daily and monthly fields and only show the weekly ones, such as day of week.
Also, if they go back and change it to daily, then the fields that are shown or enabled need to change to reflect that selection.
How would I set up the admin form so that this happens? I know this is doable through the DOM and javascript, but I am trying to determine if there is a mechanism for this built in to Django. I've been searching the Django docs, but I can't seem to find it.
Does anyone have an example showing how you have done similar things?
There's no build in solution.
Simple solution is to add custom JavaScript code to your admin. See the reference here. Simply add the js and css files to the Admin class and script the form in your custom js.
class ReportAdmin(admin.ModelAdmin):
class Media:
js = (
'frontend/js/jquery-1.6.1.min.js',
'frontend/js/jquery-ui.min.js',
'frontend/js/custom_js.js',
)
