In my project I am using Struts 2 with Freemarker. How can I find last action's name from inside the template?
For example:
* I have one FTL file for adding and editing the object,
* I would like to be able to find last actions name eg. ${actionContext.actionName}.
Is there a way to do that?
I have manually rendered a lastAction hidden form field set to the current action's name. It is the current action during rendering, but will become the last (or previous) action on the next request when the form POSTs or GETs.
It's been useful for me to revert back to the last action when the current user action (which could be triggered from one of several previous actions) fails for some reason.

I have a table on an index page (action) of a view with around 15 columns. Some of them are for text and some of them are for integers only. Every entry of this list (table) will be filled out by a 'form_for' form (in new or edit action).
For editing or deleting there are links with each list entry in the index view leading to the corresponding show, edit or destroy actions. This all works well. Some of these entries are entered by a select with pulldown on the new or edit view. This works well, too.
But if one of these selects should be changed for more than one entry in the list it takes too much time to click on 'edit', change the select and click on submit at each list item. To make this a better user experience I would like to be able to change the selects in the list (table) directly. It would be good to have the select/pulldown in place. The change of the state or choosen entry should than be saved in place as well or with an extra button ("save changes") above/below the table.
To say it in short:
I want to update multiple entries in a table in an index view without editig each single entry via edit view. The dates will be changed by a select and the data should be saved by a submit button on this page
Has anybody an idea how I can solve this?
Try best_in_place gem. It can solve the problem you have quoted. here are some links to it

Your original text wasn't that confusing to me...
You want what's called a bulk edit feature. Easiest way would be to set up a new target at the controller level specifically to handle this request. I'll give you the pseudocode and it should be easy enough to fill in the blanks, but essentially:
Create a "bulk edit" form (the drop down select menu above the table)
Create a controller method to handle the bulk edit (controller#bulk)
Update routes.rb to direct a URL to that new method
Handle the bulk update in the controller and redirect back to index upon completion (cheap way of updating the page after editing is done).
Note: I'm assuming your model name is "Resource" because you did not specify what it actually was
On your index page, you want HTML like:
<form method="POST" action="/resources/bulk">
<select name="bulk_value">...</select>
</form>
On change/form submit/whatever, submit that form.
If you're using resourceful routing, you can hook this into config.rb via:
resources :resources do
post :bulk, on: :collection
end
Otherwise, hook the route however you see fit.
Then, in your controller:
def bulk
value = params[:bulk_value]
Resource.update_all value: value
redirect_to {resources_path}
end
Now, you said index view, so I am assuming you want all. But if you just want a subset, you can pass the preferred IDs along with the form as a hidden field, then use a where clause to filter, i.e.
Resource.where(id: parmas[:id_array]).update_all(value: value)
Anyway, that should get you down the right path.
I have a page that is a report from a database and I'm working on modifying how the filtering works. The intention is to allow the user to select possible values form a list that will be used to filter the resulting report. There are too many values to do this with checkboxes. I'm defining a multiple selection list box with this:
<g:select name="country" from="${countryDataList.KOUNTRY}" value="${params.country}" multiple="true" />
countryDataList is a List<> of objects with a name and a value which I create in the controller. I'm able to get the selected counties and process them without an issue.
But when the page returns from the controller with the filtered report, only the first selection in the list is selected. It doesn't re-select all of the items that the user selected. I am passing the params.country object back from the controller as
country:params.country
I saw some posts about this not working, but they are all from several years ago. Am I missing a vital step?
Ahh sorry, I was reading it on the phone initially and missed the point.
So what you want is a way of sending a multiple select box to a confirmation page. If I understand correctly?
Anyways how many objects in the select are we talking massive or a dozen couple of dozen or so ?
What I did was use check boxes and did a confirmation which shows the selection ticked in check boxes.. So this is the confirmation page that loads in https://github.com/vahidhedayati/mailinglist/blob/master/grails-app/views/mailingListEmail/confirmcontact.gsp
this page which is where multiple attachments selected from the schedule re-appear...
https://github.com/vahidhedayati/mailinglist/blob/master/grails-app/views/mailingListAttachments/_mailerAttachmentsDisplay.gsp.
Please note advice below is all conceptual stuff and there may be easier ways than this
Other than that You could create a taglib call on the confirmation page https://github.com/vahidhedayati/ajaxdependancyselection/blob/master/grails-app/taglib/ajaxdependancyselection/AutoCompleteTagLib.groovy#L55 which takes in your arrayList you could probably convert it to JSON pass it into the javascript that you load in within the taglib (on mine further down it loads this page in)
https://github.com/vahidhedayati/ajaxdependancyselection/blob/master/grails-app/views/autoComplete/_selectJs1.gsp#L23
and look to reselect them using javascript... as I say I haven't tested the last bit, the first bit i.e. checkbox works it is/has been in use.
Years later from you I just had the same problem. What I figured out is: it happens when params.country is an array instead of a Collection (i.e. an ArrayList).
A workaround for this if you want to stick to the array type is at the value attribute of the tag doing this: params.country?.findAll().
I'm using ExpressionEngine and SafeCracker along with Ajax (plugin: jquery.form.js - http://jquery.malsup.com/form/).
Best I can tell, SafeCracker will only allow for updating a single entry at a time. However, the UI / UX necessitates that a list be displayed. I've proof of concept'ed an entry by entry on-demand form. That is, click a particular edit link next to each entry and a snippet of jquery creates a form along with displaying a submit button. Click submit and that single entry updates. The inputs don't exist until the Update link is clicked
What I would prefer to do, if possible, is to create the non-form and form versions of each entry as the page is renbered and use some sort of toggle to display one or the other. Again, doable. Then, when I click the Edit link I'd add the necessary attributes to the input so that entry's form elements will be read but the other (display: none) elements for the other entries will be ignored. I'm thinking (out loud) that if I add the attr("name", some-value) that would work. That is, an input with no name will be ignored.
Yes, I can test this and I will. However, even if it works I'm not sure if it's a best practice and/or there's a more ideal way of accomplishing my ends. I'm here looking for validation and/or additional expertise and input.
Thanks in advance.
Just set disabled property to inputs and they will excluded from Form submission, whatever input fields are hidden or visible. Different jQuery methods, like submit() and serialize() follow specification of HTML 4 and exclude all disabled controls of a forms. So one way is to set
$('your_input').prop('disabled', true);
or ,
$('your_input').attr('disabled', 'disabled');
Check following link:
http://www.w3.org/TR/html401/interact/forms.html#successful-controls
Also, you may use a general button instead of a submit, as result you can handle click event on it and within that event you can make exclusion, validation, manipulation on values and what ever you like.
You can put a disabled attribute on them server side or set the property via jQuery:
$(".hidden input").prop("disabled", true);
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 ;)

I've got a page that creates a ticket in our help desk system. It acts as a wizard with the following steps:
Step 1
User selects the customer from a dropdown list. There is a jquery onchange event that fires and generates the list for step 2 and hides the step1 div and shows the step2 div.
Step 2
User selects the location from a dropdown list. This is generated based on the customer selected in step 1. There is a jquery onchange event that fires and generates the list for step 3 and hides the step2 div and shows the step3 div.
Step 3
User selects the type from a dropdown list and enters text into 3 different text boxes. If the user fails to enter text or enters invalid text my controller changes the model state to invalid and returns the view.
How can I get all the dropdowns to repopulate again with the correct selection the user chose and get the page to redisplay on Step 3?
My first thought was to use ajax and when the user clicks the Create button, I could create the ticket from there and if successful send them to the ticket detail. If unsuccessful, well just display an error message and i'm still on the page so no big deal. Now that I write it out I think this is best. Are there any major issues using ajax? It seems most sites use some type of javascript or ajax these days.
Second thought is to not use ajax at all and submit all the pages to the server.
What do you suggest?
The 3 steps display completely different markup.
There is possibly not much you can gain by an AJAX-version, except the avoided page flicker when you change the steps.
If you go the non-AJAX way you gain:
nice bookmarkable links ( www.ticketsystem.com/Customer -> www.ticketsystem.com/Customer/Microsoft/ -> www.ticketsystem.com/Customer/Microsoft/Location -> www.ticketsystem.com/Customer/Microsoft/Location/Redmond )
browser history works
easier testing
To redisplay the lists after step 3 you would load all of them and set the selected item according to the parameter in the URL.
I agree with you. Use AJAX to submit the ticket.
