Make it readonly !

    &lt;%= location.text_field :country,:readonly =&gt; true%&gt;



The trick is to use &quot;object&quot; in conjunction with a label for anything you don&#39;t want to change. Here is how you should code it:

    &lt;%= location.label(:country, f.object.country) %&gt;

I&#39;m building my first Rest API which serialize data to JSON and XML formats. 
I would like to provide an index page to API clients, where they would be able to choose implemented endpoints.

What information do I need to include to make my API most useful, and how should I organize it?

I put an `Image` control on a Window and I would like to display an image that is stored in a project resource file named &quot;Resources.resx&quot;. The name of the image in the resource file is &#39;Search&#39;. 

Could someone show me how I might go about doing this?

I have a form_for written in the following manner: 

    &lt;div class=&quot;field&quot;&gt;
    	&lt;%= location.label :city %&gt;
    	&lt;%= location.text_field :city, :disabled=&gt;true%&gt;
    &lt;/div&gt;
    &lt;div class=&quot;field&quot;&gt;
    	&lt;%= location.label :country %&gt;
    	&lt;%= location.text_field :country, :disabled=&gt;true%&gt;
    &lt;/div&gt;

As you can see the 2 textfield are disabled because they are autofilled by a jquery function and I don&#39;t want let the user handle them.
The problem is that in this way, the view doesen&#39;t pass that parameters to the controller because are disabled !!!
Is there any other way to pass not editable text_field to the controller, taking care that I don&#39;t want to use hidden field because I want to show the results to the user inside a textbox

I&#39;m using an IF statement in Ruby on Rails to try and test if request parameters are set.  Regardless of whether or not both parameters are set, the first part of the following if block gets triggered. How can I make this part ONLY get triggered if both params[:one] and params[:two] is set?

    if (defined? params[:one]) &amp;&amp; (defined? params[:two])
     ... do something ...
    elsif (defined? params[:one])
     ... do something ...
    end

I want to be able to create a record in the DB but then prevent Rails from making changes from that point on.  I understand changes will still be possible at the DB level.

I believe attr_readonly does what I want on an attribute level, but I don&#39;t want to have to manually specify fields... I would rather have more of a white-list approach.

Also, I know there is a :read_only option for associations, but I don&#39;t want to limit the &quot;readonlyness&quot; of the object to if it was fetched via an association or not.

Finally, I want to be able to still destroy a record so stuff like :dependent =&gt; :destroy works in the associations.

So, to summarize: 1) allow the creation of records, 2) allow the deletion of records, and  3) prevent changing records that have been persisted.

I need to restrict input into a TextField to integers. Any advice?


What is the recommended way to make a numeric TextField in JavaFX?

I have 4 textfields on a register screen and i have it set up so that when the user presses next on each text field, the next text field is focused. Code below:

    func textFieldShouldReturn(textField: UITextField) -&gt; Bool {
        if (textField == self.fNameField) {
            textField.resignFirstResponder()
            self.sNameField.becomeFirstResponder()
        }
        else if (textField == self.sNameField) {
            self.emailField.becomeFirstResponder()
            
        } else if (textField == self.emailField) {
            self.passwordField.becomeFirstResponder()
        }
        else {
            var thereWereErrors = checkForErrors()
            if !thereWereErrors
            {
                //conditionally segue to next screen
            }
        }
        
        return true
    }

On the return of the final text field, I am calling a check for errors function (below). Within that if there is an issue with any field I want to focus that text field so the user can easily correct it. What is happening is that the text field with the error is focusing (as instructed by the checkForErrors functions)for a second but then the focus is switching back to the password text field. I also tried adding in `self.passwordField.resignFirstResponder()` into the last else of the above function and that makes the password field lose focus but then the text field with the issue encountered is not gaining focus at all (not even for a second as before) How can I fix this?

    func checkForErrors() -&gt; Bool
    {
        var errors = false
        let title = &quot;Error&quot;
        var message = &quot;&quot;
        if fNameField.text.isEmpty {
            errors = true
            message += &quot;First name empty&quot;
            alertWithTitle(title, message: message, ViewController: self)
            self.fNameField.becomeFirstResponder()
        }
        else if sNameField.text.isEmpty
        {
            errors = true
            message += &quot;Surname empty&quot;
            alertWithTitle(title, message: message, ViewController: self)
            self.sNameField.becomeFirstResponder()
        }
        else if emailField.text.isEmpty
        {
            errors = true
            message += &quot;Email empty&quot;
            alertWithTitle(title, message: message, ViewController: self)
            self.emailField.becomeFirstResponder()
        }
        else if !isValidEmail(emailField.text)
        {
            errors = true
            message += &quot;Invalid Email Address&quot;
            alertWithTitle(title, message: message, ViewController: self)
            self.emailField.becomeFirstResponder()
        }
        else if passwordField.text.isEmpty
        {
            errors = true
            message += &quot;Password empty&quot;
            alertWithTitle(title, message: message, ViewController: self)
            self.passwordField.becomeFirstResponder()
        }
        else if count(passwordField.text.utf16)&lt;8
        {
            errors = true
            message += &quot;Password must be at least 8 characters&quot;
            alertWithTitle(title, message: message, ViewController: self)
            self.passwordField.becomeFirstResponder()
        }
        
        return errors
    }

Note I have included the textField delegate.

alert with title function as requested:

    func alertWithTitle(title: String!, #message: String, #ViewController: UIViewController) {
        let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
        let action = UIAlertAction(title: &quot;OK&quot;, style: .Cancel, handler: nil)
        alert.addAction(action)
        ViewController.presentViewController(alert, animated: true, completion: nil)
    }

Disable a text edit field in flutter

The TextField widget doesn&#39;t seem to have a &quot;limit&quot; attribute to limit the number of characters that can be typed. How I can enforce that only a certain number of characters can be provided as input in a TextField Widget. I tried looking at the decoration property and potentially setting the limit there somehow but that didn&#39;t seem to work either. Is there a different widget I should be using?

    &lt;/div&gt;

This generates the label &quot;Name&quot;, but I want it to be &quot;Your Name&quot;. How can I change it?
