I am doing a module using modal windows, where in the index I am showing all the records, saving data, editing and deleting everything using ajax. Pressing the respective buttons in the row of each record opens the modal window depending on the button. But I would like to press the "edit" button to send the log id to the controller, search the data and return it in the modal window. To send the id to the controller should I place a form on each button?
A traditional non-AJAX edit button that you would typically see in a Rails index page would look something like this:
<td><%= link_to 'Edit', edit_thing_path(thing) %></td>
You would need to do three things to AJAX-ify this:
change the link_to so that it sends an AJAX request instead,
get the things_controller#edit method to respond with JSON,
write some JS that picks up the JSON response from the server, and populates it in the modal's form.
An alternative approach, which might be easier, would be to use UJS as recommended by the Rails core team. In this case:
change the link_to to request a JS response
change the controller's edit method to respond by rendering a JS file
build a JS file that renders the modal server, side, and then replaces the current modal in your HTML with the newly-built modal form, and then
reveal the modal in the page
Have a look here in the Rails Guides (for Rails v4.2).
To do that I really like to use Best In place its supper simple to use and implement.
there is also a video on how to use it, its a bit old 302-in-place-editing

Pretty stumped at the moment trying to figure something out. I have a modal that shows a table, and for each of the entries in the table, I have actions (i.e., show, edit, delete, etc). When the user clicks on "Edit" for an entry row in this model, I want it to populate another model with a form to show the data associated with that entry.
Is there a convenient way to do this? For one, I do not know how to pass a parameter to a modal from another modal. I don't know how to make this form "reinitialize" after it's already been rendered when the first page is loaded.
Any suggestions?
I have been in the same situation and I suggest that you just keep the one modal and replace the contents through AJAX (IMO). Once you have rendered into the modal in the first place, your links can then just render as AJAX the same way that they would and overwrite the information inside the modal. The way I did it was this:
Populate the modal (you've already done that).
Create a link = link_to "Text", "url", remote: true (let's say this is the edit action).
Run the edit action in the controller as usual.
The edit.js.erb file would contain one line: $('#Modal_content').html("<%= j render 'edit' %>") (#Modal_content is just a div that I put in my modal so that I can replace all the contents without messing up the close button and other modal required html).
The _edit.html.erb file is called where you would put all of what you needed that comes from the edit action.
As for passing information, the id is passed through the link that you click on to call the controller#edit action.
Let me know if you need more details, but that should get you most of the way there.
I am trying to implement two pages. The first page being a selection of the items I want to show on the second page.
On my first page, I have done a selection of the items which I want to render.
On click of a button, 1. the ids of these items will be placed in an array and 2. the user will be redirected to a new page through:
window.location.replace("/schedule");
Right now, I want to achieve the following:
Do an ajax call through rails to get each of the array items. i.e. make an ajax calls to the urls of myclass/[id]. The id belonging to the items in the array.
I am not sure how I could get my array items from the current page to the next page or if there is a better way of achieving this. Any advice or suggestion will be greatly appreciated.
Add :remote => true to your form. Then, app will render your action_name.js.erb view instead of action_name.html.erb. In js file you can put code, which will repleace div without redirection, f.e.
$('#div_id').html('<%= escape_javascript render(your_partial_name) %>');
You don't need to do anything special in partial and controller action, its all the same.
I'm looking to display my flash messages in a portion of the page that is otherwise not always in a partial that gets updated.
In other words, I may submit a form that updates a partial via ajax. But I want to display the flash message in a portion of the page that is outside of that partial.
I could have some javascript in every single necessary js.erb file to update the flash partial, but that seems crazy. Is there a more simple way of going about this?
I don't have to necessarily use flash messages either if something custom would work better.
Thanks!
You can do it the low-tech way by using a :remote call on your form that, when executed, will inject some HTML back into your page from a partial of your choosing.
It's pretty easy to do in a .rjs view:
page['flash'].html(render(:partial => 'flash'))
You can also do it in a .js.erb view using jQuery:
$('#flash').html("<%= escape_javascript(render(:partial => 'flash')) %>");
I tend to think the .js.erb method is a lot more ugly, but we all have our preferences.
I have a view 'edit.html.erb' which renders a partial.
<div id="exerciseslist"><%= render 'exerciseslist' %></div>
Inside 'edit.js.erb', I have the following line which reloads the partial each time something is updated.
$('#exerciseslist').html('<%= escape_javascript(render("exerciseslist")) %>');
The partial is a table with a bunch of items including images for each one and some buttons. All that is changing in the partial is the button. If a submit is successful, the button toggles state indicating that it has been added.
It's working fine, the problem is I don't like the way the images flash as the request happens, the items are also inside a scrollable section which looses it's state each time.
Is there a good way to just load the state of the buttons without rendering the full partial? Or is there a simple way to stop the client requesting the images each time?
I have done some reading and found pjax and backbone.js, are either of them a good way or is there a simpler rails way to do this?
Thanks,
Mike
Without seeing code, it's hard to be sure, but I think it could be done with just Rails. Instead of re-rendering the exerciseslist partial on submission, you could write an AJAX request to handle submission of the new data and on success, have the callback change the button state, rather than reload the partial.
I am looking for the best way to create ajax enabled subforms from items in a list with MVC 3. A static list of values should be generated, but with an "edit" link/button next to every item, to toggle inline edits.
I did follow the tutorial at this link
http://blog.janjonas.net/2011-07-24/asp_net-mvc_3-ajax-form-jquery-validate-supporting-unobtrusive-client-side-validation-and-server-side-validation [1]
However it is based on the form edit fields always being visible
I'd like to show a static list with field values, but let the user activate an edit field by clicking "edit" (e.g. button)
I did modify the example at [1] by creating a default partial view with a form with submit button only. When posting the data by ajax the edit form will show. It looks like it is working, (I only need to hide validation errors on the first POST - which does not send real data).
Update:
An even better solution would probably be to leave out all forms in the static view, just have a single css class button/link next to each item, and let jquery fetch the relevant view for the clicked item. I am not sure how to do that with MVC 3+jQuery though.
Another update:
I discovered Ajax.Actionlink, which did exactly what I wanted!
I found out how to do it, and it turned out to be real simple!
I created two partial views.
One for rendering each static item. I used used Ajax.ActionLink with InsertionMode "replace", and set the parent of the item as the target
The second for rendering the form. Here I used Ajax.Beginform with similar options.
On successfully saved data, I returned the static view, on failure, I returned the partial view with the ajax form again.
I'm happy I found a MVC-centric way to do it (although it is fun creating custom stuff with jQuery)
It sounds like you need an inline editing plugin for jQuery. I would try jEditable. I have not used it myself but appears to have extensive docs.
this entry might help: code + video + explanation ;)
