Save and do nothing

[DrunkeN]

Hello guys,

what i have to tell the controller that he just save the Textfields into the Database but without any redirection when i click on the Save button?

The only thing what should happen is that it will be saved in the Database and nothing more.

This is the standard save Controller class, what do I have to change?

    def save() {
                def myInstance = new Myparams)
                if (!myInstance.save(flush: true)) {
                        render(view: "create", model: [myInstance: myInstance])
                        return
                }

                flash.message = message(code: 'default.created.message', args: [message(code: 'my.label', default: 'Allgemein'), myInstance.id])
                redirect(action: "page1", id: myInstance.id)
    }

When I redirect to page1, then all my textfield data are gone from the textfields, but they are in the Database.

Can you help me please. Regards

You should use ajax as described in http://grails.org/doc/latest/guide/theWebLayer.html#ajax

Hy MIchael,

thank you for your help, but when I try something of the exercises, an error appears.
Do I have to add something in a folder when I add this <g:javascript library="jquery" /> in the head tag?

Because I always get this error:

HTTP Status 405 -

--------------------------------------------------------------------------------

type Status report

message

description The specified HTTP method is not allowed for the requested resource ().


--------------------------------------------------------------------------------

Apache Tomcat/7.0.25

Yes, add

    <g:javascript library="jquery"/>

inside the head section and add

   grails.views.javascript.library="jquery"

in Config.groovy, if not allready defined.

Hi MLoe,

I did it, but the same error appears. Unfortunately the Grails website is down and I cannot read the instructions. :/

Hi again.

OK, jquery is running now, but I didn't get it. I don't know how to write the code.

I have a button in  the view which should save the textfields and checkboxes into the DB:

                                        <g:remoteLink class="button" action="ajaxsave" value="${message(code:
                                                'my.button.save', default: 'Save')}" />

Is that correct for jquery?

and then I have this function:

- when i run it, there is nothing in the DB so i have to call a save function and not an update.
- my identifier (primariy key is the ID

the problem is, when i have nothing saved before, i have no ID:

                def ajaxsave() {
                        def myInstance = new My(params)
                        render(view: "create", id:myInstance.id)
                }

Well this does not work. Is there a good tutorial or can someone help me? The only thing what the button should do is to save the values in the textfields into the DB and nothing more. No page reloading, no forwarding to another page, nothing.

The controller action should not render the complete view

   render(view: "create", id:myInstance.id)

but only a part of your view using a template

see http://grails.org/doc/latest/ref/Controllers/render.html

Hm, when I try this:

                def ajaxsave() {
                        def myInstance = new My(params)
                        render( template: "form", id: myInstance.id) // or render( template: "form", id: myInstance.id)
                }

It doesn't work either. The main problem is, that the data in the form (textfields and checkboxes) is not in the fields any more.

Is there any other solution?

g:remoteLink is GET request to fetch the data, to submit your data you should use formRemote or submitToRemote

There are several way to submit your data using ajax and jquery.
jQuery.ajax({
                url: $(form).attr('action'),
                data: $(form).serialize(),
                type:'POST',
                success: function(data) {
                   // Do your success actions
                }
            });

Hi Lok,

sorry but I am totally new to jQuery and Ajax. Where is this code located? In the head tag?

When i put this into my gsp file:

jQuery.ajax({
                url: $(form).attr('ajaxsave'),
                data: $(form).serialize(),
                type:'POST',
                success: function(data) {
                   // Do your success actions ?? - my success action should be to load the textField data into the DB, I hope I am not wrong.
                }
            });
