I am trying to build a ROR app that allows users to enter date in various formats such as 12/31/11 (month/day/year) or 31/12/11 (day/month/year). In order to interpret date format, I will have a select field from where user can select the format of date. I can use Date.strptime(value, format).to_s() in controller before saving record.
However, I am not sure is controller right place to put this information. Is there a way I can push this to model..say in before save method.
You could just save the data as it is (in the controller), and have another field in the model telling it how to interpret the data. Then, in a before_validation callback, you could try parsing the date according to the given format and writing it to the same field, now as a date. Problems may arise on the way back. Then, to display it in the view again, you could write helpers - but better yet, provide a method in the model (for instance, formatted_date) that will compute and display the date.
However, this requirement sounds strange. Why is the user's responsibility to select a date format? Shouldn't it be based on the user locale?
In any case, I suggest you register your date formats in an initializer, rather than repeting the format strings throughout the application.

I'm writing a form where some additional processing is required before sending the values. The image below depicts the simplified example.
where test_date and remind_date are saved on the server as a string of format YYYY/MM/DD.
However, the text field shown above allows users to enter an integer. The value from this field needs to be processed (basically, test_date - form_value).
I'm currently doing this conversion before sending the value to the server, within a saveForm() function that is triggered when the Submit button is pressed.
I feel like this might not be the ideal way, and wanted to get your opinions. Would it be better to handle this within the controller, by allowing a new param?
For a simple field like this you can just create another instance variable in the controller.
For more complex calculations or additional fields you could use a form object, eg: using the https://github.com/andypike/rectify gem or Reform.
For a blog model I'm saving an RSS field as text under Blog.rss, problem is, some of this is rather long and each one prints when I'm working in the rails console, ie: Blog.last(10).
Is there a way to hide output unless I call someblog.rss specifically?
I had a similar problem and received some solutions in another forum, which were:
Use select to get just the columns you need
If you have a very long column (I had JSON data structure from a webhook cluttering the console), consider whether you really need it, and if you don't , don't store it in the table
Or, consider storing it in an associated table
if you need the whole object but just want to change how it's represented in console/log output, you can redefine inspect
yourobject.as_json(except: :unwanted_column)

I have several datetime_field in my application. By default, they are displaying the date as the rails format, as I dictated that for my bootstrap-datepicker:
format: 'YYYY-MM-DD HH:mm:ss'
The issue: I want the date on the views to display in a different format, say:
'MM-DD-YYYY HH:mm:ss'
I've been scratching my head for a while on this one. Every change I make to the view side, be it by Javascript, jQuery, rails methods, helpers, whatever - they all affect the submit data, which then becomes invalid, because Rails expects the first format.
I don't want to change the default date format - we have other aspects of the website that need the database in the normal rails format. I just want to change the display of the date in the datetime_field, without changing the submitted date.
My guess would be it was an option in the datetime_field, but I can't seem to find one:
<%= f.datetime_field(:end_date, {?????})%>
Any suggestions on how to accomplish this?
I have a datetime value which comes from the API in this format: 2015-07-07T17:30:00+00:00. I simply want to split it up between the date and time values at this point. I am not using an Active Record model and I prefer not to use an sql database if I can.
The way I have set up the app means that the value is "stored" like this in my view: #search.dining_date_and_time
I have tried two approaches to solving this problem:
Manually based on this previous stackoverflow question from 2012: Using multiple input fields for one attribute - but the error I get is the attribute is "nil" even though I put a "try"
Using this gem, https://github.com/ccallebs/split_date_time which is a bit more recent and seems to be a more elegant solution, but after closely following the doc, I get this error, saying my Search model is not initalized and there is no method: undefined method dining_date' for #<Search not initialized>
This is when instead I put #search.dining_date in the view, which seems to be the equivalent of the doc's example (its not that clear). The doc also says the method will be automatically generated.
Do I need to alter my model so I receive the data from the API in another way? ie. not get the variable back as #search.dining_date_and_time from the Search model for any of this to work?
Do I need an Active Record model so that before_filter or before_save logic works - so i can (re)concatenate after splitting so the data is sent back to the API in a format it understands. Can I avoid this - it seems a bit of overkill to restructure the whole app and put in a full database just so I can split and join date/time as needed.
Happy to provide further details, code snippets if required.
As I am not using a conventional Rails DB like MySql Lite or Postgresql, I found that the best solution to the problem was by using this jQuery date Format plugin: https://github.com/phstc/jquery-dateFormat to split the date and time values for display when I get the data back from the API.
The Github docs were not too expansive, but once I put the simply put the library file in my Rails javascript assets folder, I just had to write a few lines of jQuery to get the result and format I wanted:
$(function() {
var rawDateTime = $('#searchDiningDateTime').html();
// console.log(rawDateTime);
var cleanDate = $.format.date(rawDateTime, "ddd, dd/MM/yyyy");
// console.log(cleanDate);
$('#searchDiningDateTime').html(cleanDate);
var cleanTime = $.format.date(rawDateTime, "HH:mm");
// console.log(cleanTime);
$('#searchTime').html(cleanTime);
});
Next challenge: rejoin the values on submit, so the API can read the data by sending/receiving a valid request/response. (The values can't be split like this when sent to the remote service).
I am trying to format an input field of the type xs:date in Orbeon.
I have tried using the xxf:format attribute, but the datepicker can not understand the date when it has been modified.
The idea now was to change the javascript of Orbeon to use the xxf:unformat attribute to interpret the date and transform it back to ISO format.
I've tried changing the data.js but for some reason none of the changes can be seen.
Am I changing the wrong file?
Edit
I figured out that the xforms.js has a function 'getCurrentValue' which is being as the changes I do there are visible. Now I just need to figure out who is the one that's calling the function.
Edit:
It is the Calendar who requests the value of the input when the user clicks on the symbol. This all happens at the client side, and the generated HTML does not have the format/unformat attributes. However I want to use their value. Can I make a request to Orbeon to get it? How?
In case you're using an xf:input bound to a node of type xs:date, you can control the formatting of the date field with the oxf.xforms.format.input.date property. A few formats are supported, and if you want to add more, the best would be to follow the pattern currently used for the currently supported formats.
E.g.
[M]/[D]/[Y]
[Y]-[M01]-[D01]
