Hi I encountered a problem with ng-model. I want to create an edit page for admin user to edit the rest of the user's permission level.
So, I listed out all the user's attributes in the edit page, and these attributes should display the current values.
I can update all the attributes correctly, however, the problem is that when visiting the edit page, only certain attributes are displayed while some are not. I think it is the problem with ng-model.
code snippets from my _form.html.erb
<div class="col-md-12 space-1" ng-class="{ 'has-error' : form['email'].$invalid }">
<label class="control-label">Email</label>
<div class="input-icon right">
<i ng-show="form['email'].$invalid" class="fa fa-warning tooltips" data-original-title="{{errors['email']}}" data-container="body"></i>
<input ng-model= "user.email" name="email" type="text" class="form-control">
</div>
</div>
<br>
<div class="col-md-12 space-1" ng-class="{ 'has-error' : form['events'].$invalid }">
<label class="control-label">Event Permission Level : {{user.activities.events}}</label>
<div class="input-icon right">
<i ng-show="form['events'].$invalid" class="fa fa-warning tooltips" data-original-title="{{errors['events']}}" data-container="body"></i>
<input ng-model= "user.activities.events" name="activities.events" type="range" max="2" min="0" class="form-control">
</div>
</div>
<br>
<div class="col-md-12 space-1" ng-class="{ 'has-error' : form['admin_events'].$invalid }">
<label class="control-label">Admin Event Permission Level : {{user.activities.admin_events}}</label>
<div class="input-icon right">
<i ng-show="form['admin_events'].$invalid" class="fa fa-warning tooltips" data-original-title="{{errors['admin_events']}}" data-container="body"></i>
<input ng-model= "user.activities.admin_events" name="activities.admin_events" type="range" max="2" min="0" class="form-control">
</div>
</div>
<br>
The code above shows 3 different ng-models, 1.user.email, 2.user.activities.events 3.user.activities.admin_events
The way I process them is the same, but when visiting the edit page, only email and events attributes displayed the current value, but not admin_events. I can update their values alright, but I cannot get admin_events to display its current value when visiting the edit page. This is weird isn't it. I mean if I can see the value of events, why can't I see the value of admin_event since they all belong to the user variable.
Can anyone explain why is it like this? It is very confusing for me. Thank you very much.
As it solved the problem, I quote myself from the comments :
If only user.activities.admin_events is not working, it may be related to the _ notation. Try camel case user.activities.adminEvents or user.activities['admin_events'].

New to materializecss, trying to read radio button and not having any luck.
<form class="main" id="sponsorform" novalidate="novalidate" style="max-width: 480px;margin: 40px auto;">
:
<div>
<div class="row">
<div class="input-field col s12">
<p>Choose race to sponsor</p>
<p>
<input type="radio" name="race" id="wdf">
<label for="wdf">Women's Distance Festival</label>
</p>
<p>
<input type="radio" name="race" id="msm">
<label for="msm">Market Street Mile</label>

</div>
<div class="row">
<div class="input-field col s6">
<button class="waves-effect waves-light btn submit-btn" type="submit" onclick="nextOrSubmitPage(); return false;">Next</button>
</div>
</div>
</div>
When I click on one of the options, the circle gets highlighted but using chrome inspect I do not see any change to the dom.
And when I try to read I see either
$('input[name=race]:checked').val()
"on"
or I get an error `Cannot read property 'val' of null
Not sure what changes in between the two behaviors, though.`
Note: this is all within google apps script. Not sure if that is relevant or not.
Ok, after some hacking around, I found the following seems to work
$('input[name=race]:checked').attr('id')
Not sure if there's a better way to do this, but as I said it seems to work.
This may solve your problem.
$("input[name=group1]:checked").next().text();
OP Update
I've figured out the problem and this issue is now closed. Would one day like to find the time to post the solution as an answer here.
I'm having a bit of an issue working with ngMessages inside an ng-form on an Angular Bootstrap tab. Further complicating things, the thing I am validating is a Angular Bootstrap datepicker. So the code is as follows, and as you can see, I've got a datepicker on an ng-form which is on a Tab.
<uib-tab index="5" heading="{{tabs[5].title}}" select="changeCheck($event)">
<ng-form name="{{tabs[5].form}}">
<div class="col-md-9">
...
<div class="col-md-6">
<h4>Add Followup</h4>
<div class="form-group">
<label for="addFollowupDate" class="control-label">Date:</label>
<div class="input-group">
<input type="text" id="addFollowupDate"
class="form-control"
uib-datepicker-popup="{{format}}"
ng-required="true"
ng-model="newFollowup.date"
is-open="addFollowupPopup.opened"
datepicker-options="dateOptions"
close-text="Close"
alt-input-formats="altInputFormats" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="openAddFollowupPopup()"><i class="fa fa-calendar"></i></button>
</span>
<div class="help-block" ng-messages="followupsForm.newFollowup.date.$error" ng-if="followupsForm.newFollowup.date.$invalid && followupsForm.newFollowup.date.$touched">
<div ng-message="required">This field is required</div>
</div>
</div>
</div>
I've assigned that form to the scope using the following line:
$scope.followupsForm = $('ng-form[name="followupsForm"]').data('$formController');
And I have successfully set the control to touched on a submit which does make the border go red:
if ($scope.followupsForm.$invalid) {
angular.forEach($scope.followupsForm.$error, function (formErrorField) {
angular.forEach(formErrorField, function (errorField) {
errorField.$setTouched(); // by setting to touched, the relevant message will display if the field is invalid.
});
});
}
But the ng-message for required does not display.
Any ideas why? Could be a tough one with nested scopes etc. (of the tab and the picker).
I am using Firebase in a pretty simple chat application. One of the features i'm working on now is the ability to update messages in the chat room, but only if you were the original author. For the editing i have an icon that, when clicked, will do some javascript to hide the message div and display a previously hidden div that has the update form in it. But i only want this to be available if you were the author of the message. Here's what the code looks like:
<li class="message phm pvm pull-left" ng-repeat="(msgId,msg) in room.messages">
<div class="message-current" data-message-id="{{msgId}}">
<span class="message-author pull-left">{{msg.author}}</span>
<span class="message-body pull-left pls">{{msg.body}}</span>
<span class="message-timestamp pull-right prs">
{{msg.timestamp | date:'MMM d, yyyy h:mm a'}}
<a class="message-update-link" href="#" ng-click="showMessageUpdate(msgId)"><span class="glyphicon glyphicon-pencil"></span></a>
</span>
</div>
<div class="message-update hidden" data-message-id="{{msgId}}">
<form class="form-inline" ng-submit="updateMessage(roomId, msgId, '<%= current_user.full_name %>')">
<textarea class="form-control update-message" ng-model="msg.body" ng-trim="false">{{msg.body}}</textarea>
<input class="button button-large button-primary" type="submit" value="Update">
</form>
</div>
</li>
Right now, i can only get it to have updatable message for ALL message or no messages. Basically, the part i am stuck on is the check of whether or not the angularjs value of {{msg.author}} is equal to the rails value of <%= current_user.id %>. Any thoughts on how this can be achieved? Thanks for any help!
SOLVED:
Thanks to Jiten for the step in the right direction. I'm new to learning AngularJS and it's pretty complex. Sometimes you just need to know where to start.
I ended up using a combination of the ngIf directive and the angular.equals function. In my rails view i used ng-if="isAuthor(msg.author, '<%= current_user.full_name %>')" on anything i wanted available to authors of that message only. This will evaluate the response of isAuthor() and only render to the dom if it evaluates to true. The code above now looks like this:
<li class="message phm pvm pull-left" ng-repeat="(msgId,msg) in room.messages">
<div class="message-current" data-message-id="{{msgId}}">
<span class="message-author pull-left">{{msg.author}}</span>
<span class="message-body pull-left pls">{{msg.body}}</span>
<span class="message-timestamp pull-right prs">
{{msg.timestamp | date:'MMM d, yyyy h:mm a'}}
<a ng-if="isAuthor(msg.author, '<%= current_user.full_name %>')" class="message-update-link" href="#" ng-click="showMessageUpdate(msgId)"><span class="glyphicon glyphicon-pencil"></span></a>
</span>
</div>
<div ng-if="isAuthor(msg.author, '<%= current_user.full_name %>')" class="message-update hidden" data-message-id="{{msgId}}">
<form class="form-inline" ng-submit="updateMessage(roomId, msgId, '<%= current_user.full_name %>')">
<textarea class="form-control update-message" ng-model="msg.body" ng-trim="false">{{msg.body}}</textarea>
<input class="button button-large button-primary" type="submit" value="Update">
</form>
</div>
</li>
Here is what isAuthor() looks like in my AngularJS controller:
$scope.isAuthor = function(msgAuthor, currentUser) {
return angular.equals(msgAuthor, currentUser);
}
Pretty simple really!
To compare two objects you can use:
angular.equals({{msg.authorId}}, <%= current_user.full_name %>)
I need some advice how is a recommended way to handle Twitter Bootstrap fields with Thymeleaf. I know that recommendations are not so easy, so I wrote my thoughts about it and hope you can comment it. At the end there a some concrete questions.
First I tried a fragment which shows what is needed to generate
<div th:fragment="textfield">
<div class="control-group"
th:classappend="${#fields.hasErrors('__${fId}__')}? 'error'">
<label class="control-label" th:for="${fId}"
th:text="#{model.__*{class.simpleName}__.__${fId}__}+':'">
FirstName
</label>
<div class="controls">
<input type="text" th:class="${inputclass}" th:field="*{__${fId}__}" th:disabled="${disabled}"/>
<span class="help-inline" th:if="${#fields.hasErrors('__${fId}__')}"
th:errors="*{__${fId}__}"></span>
</div>
</div>
</div>
which can be used with
<div class="control-group replace" th:include="templates::textfield" th:with="fId='userId'" th:remove="tag">
<label class="control-label replace">Benutzer-Id</label>
<div class="controls replace">
<input type="text" value=""/>
</div>
</div>
or in short
<div class="control-group replace" th:include="templates::textfield" th:with="fId='userId'" th:remove="tag"/>
It's not very flexible about the input, so you need for a checkbox an own fragment.
Next I choose the layout-approach:
<div layout:fragment="bsfield">
<div class="control-group" th:classappend="${#fields.hasErrors('__${fId}__')}? 'error'">
<label class="control-label" th:for="${fId}"
th:text="#{model.__*{class.simpleName}__.__${fId}__}+':'">
FirstName </label>
<div class="controls">
<span layout:fragment="bsinput" th:remove="tag">
<input type="text" class="replace" th:field="*{__${fId}__}" th:disabled="${disabled}"/>
</span>
<span class="help-inline" th:if="${#fields.hasErrors('__${fId}__')}"
th:errors="*{__${fId}__}"></span>
</div>
</div>
</div>
Which is very flexible because I can define my input directly.
I can use it shortly with
<div layout:include="templates::bsfield" th:with="fId='firstName'" th:remove="tag">
<div layout:fragment="bsinput">
<input type="text" th:field="*{__${fId}__}" th:disabled="${disabled}"/>
</div>
</div>
or more prototype style
<div class="control-group" layout:include="templates::bsfield" th:with="fId='lastName'" th:remove="tag">
<label class="control-label" th:remove="all">Last Name</label>
<div class="controls" th:remove="tag">
<div layout:fragment="bsinput">
<input type="text" th:field="*{__${fId}__}" th:disabled="${disabled}"/>
</div>
</div>
</div>
Both variants has still a lot of boilerplate. So I think about the following solution inspired by Playframework helper.
<input type="text" th:bsfield="firstName" th:disabled="${disabled}"/>
and writing a Processor which creates
<div class="control-group"
th:classappend="${#fields.hasErrors('${fId}')}? 'error'">
<label class="control-label" th:for="${fId}"
th:text="#{model.__*{class.simpleName}__.${fId}}+':'">
FirstName </label>
<div class="controls">
<input type="text" th:class="${inputclass}" th:field="*{${fId}}" th:disabled="${disabled}"/>
<span class="help-inline" th:if="${#fields.hasErrors('${fId}')}"
th:errors="*{${fId}}"></span>
</div>
</div>
and replace ${fId} with the value of bsfield in this example "firstname". After that Thymeleaf should recompute it (setRecomputeProcessorsImmediately (true);) For the prototype I think it's necessary to write a JS-Solution.
I'm unsure if this is really clever or a misuse of Processors. Furthermore I'm unsure how much time a beginner need to write such a processor. Are 4 hours realistic or more a few days?
Would appreciate if someone can give me a hint.
In the meantime I did it. As a beginner you must calculate 4-8 hours, without JUnit tests (it looks difficult to test processors) and DTD and editor-support. The most problems I had was that it's difficult to reuse an existing node after changing attributes. Here it's better to clone it.
Next time I think I can do it in 1 or 2 hours.
The experience is very good, you have clean and short code. With the JS-File you don't lose the prototyping experience.
I am using bootstrap-sass 2.0.0 in my gemfile, but I am having trouble getting both prepended and appended content added to an input tag in a form to work.
I got on FireBug with FireFox and copied the exact html that they use for the example on the twitter bootstrap site, copied here:
div class="control-group">
<label class="control-label" for="appendedPrependedInput">Append and prepend</label>
<div class="controls">
<div class="input-prepend input-append">
<span class="add-on">$</span>
<input id="appendedPrependedInput" class="span2" type="text" size="16">
<span class="add-on">.00</span>
</div>
</div>
</div>
But I get the prepended text facing the wrong way (it looks like the appended tag) so it kind of looks like this: [span)[.....input....][span) instead of this: (span][.....input.....][span) .
Also appended buttons do not register as being appended (also with copied code from the example) like so: (....input....) (button) instead of (....input.....][button)
Any ideas on how I can get to this: (span][....input....][button) ? I already tried the code below:
<form class="form-inline">
<div class="control-group">
<div class="controls">
<div class="input-prepend input-append">
<span class="add-on">Search</span>
<input id="search" class="input-xlarge" type="text" size="16">
<button class="btn" type="button">Go!</button>
</div>
</div>
</div>
</form>
I appreciate any and all help!
You have the right idea, you just have to put everything that is either to be appended/prepended or have something appended/prepended to it on one line with no spaces.
Like this:
<form class="form-inline">
<div class="control-group">
<div class="controls">
<div class="input-prepend input-append">
<span class="add-on">Search</span><input id="search" class="input-xlarge" type="text" size="16"><button class="btn" type="button">Go!</button>
</div>
</div>
</div>
</form>
I tested this on my own Bootstrap setup and it displays properly.
