The default rails datetime form builder provides the following form elements as select boxes...
[YYYY] [MONTH] [DD] - [HH]:[MM]
... in 24 hour time.
I would like to present my users with:
[MON.] [DD] [YYYY] - [HH]:[MM] [AM/PM]
How do you do that?
datetime_select helper has lots of different options. I never bothered to remember them all so I use this apidock page as a reference (datetime_select and date_select have similar options).
In you case, you'll need to set :order array, :ampm to true, etc.
Edit: ok, I actually bothered to write the option hash you'll need:
date_select("question", "answered_at", :ampm => true, :order => [:month, :day, :year], :use_short_month => true)

How do I set different css classes for the different selects(day, month) generate by:
<%= f.input :birthday, :as => :date, :discard_year => true,
:order => [:day, :month] %>
I just found a way to set the css class for the overall input.
It doesn't have to be simple_form. It can be regular rails code too.
Unfortunately, there is no simple way to solve it with select_date, even with simple-form. simple-form maps :as => 'date' to date_select.
Although you can split date_select into a select_day and select_month inputs and pass the respective css class at html_options for each input.
Is it possible to somehow use the :selected option that you'd use on a normal select view helper with the grouped_collection_select function? I'd like to set the value that gets pre-selected in my list. I've tried passing in :selected as an option with no luck!
Here's some code snippts of my tests:
grouped_collection_select 'user[subscription_attributes]', :subscription_plan_id, Trade.order(:name).all, :subscription_plans, :name, :id, :display_name, { :include_blank => true, :selected => 5 }
grouped_collection_select 'user[subscription_attributes]', :subscription_plan_id, Trade.order(:name).all, :subscription_plans, :name, :id, :display_name, :include_blank => true, :selected => 5
Neither version works. No selected is set. I'm using this to set a value for a nested model. I'm using the railscasts dynamic select list methods: http://railscasts.com/episodes/88-dynamic-select-menus-revised
I couldn't get formtastic to play nicely with the group selects so I had to do it by hand but I don't keep this value selected when a user fails validations. I'd like to keep this set when they fix validation errors.
I just ran across the same problem and solved it using the option_groups_from_collection_for_select helper and the select helper documented at: http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html.
The first step is to create the grouped options. Taking your example, it should look like:
<% options = option_groups_from_collection_for_select(Trade.order(:name).all,
:subscription_plans, :name, :id, :display_name, 5) %>
Then I created the select object like:
<%= select('user[subscription_attributes]', :subscription_plan_id, options,
include_blank: true) %>
You could write it all out in one line, I just broke out the options into a separate variable to illustrate the two different methods.
Maybe too late, but the API documentation of grouped_collection_select states:
'The value returned from calling method on the instance object will be selected.'
So, you don't even have to specify a :selected option, since Rails will automatically select based on the current value of your attribute.
If subscription_plan_id has value 5, then that's what will be selected.
If that's supposed to be a default value, then you can set it with an after_initialize in your model.
Actually you need to send in options include_blank for example
<%= grouped_collection_select :id, model.all, options = {:include_blank => 'Selecione'}%>
I need formtastic to display only month and year fields, WITHOUT the day fields.
The datepicker is nice but it shows the whole calendar. I don't want the datepicker.
f.input :accounting_month, :label => "Accounting month", :as => :datepicker
All I need is the month and year.
There is a way to do this:
<%= f.input :accounting_month, :label => "Accounting month", :order => [:month, :year]
This will automatically hide the "day" input and give it a default value of 1.
try this
f.input :accounting_month, :as => :date_select, :discard_day => true
It doesn't work that way because without day this implies 28-31 (depending on month) days and it could be any one of them. If you use want to store a month-year selection without day you'll see it is a range of dates, not "a" date.
Advice with dates is to always store the whole date as a date field. If you only know month and year you'll need to have two (non-date) fields, one for each. But as you can see it's going to lose you a lot and you'll need to custom craft each field, validate it, etc. major pain so needs pretty good reason to do it..
The only other thing I can suggest is:
create a hidden div, or apply css if you can't 'get inside' the standard date field on the form, for the 'day'. Then set the value to always be 01. Then you might have a 'date' set of fields that will save 01-month-year to the database. This is definitely a 'hack'!
With the new syntax in Ruby 1.9
f.input :date, as: :date_select, discard_day: true
I have created a custom date_Select field using 3 separate select fields:
<%= f.select :day, options_for_select(User::DAYS), :include_blank => "Day:" %>
<%= f.select :month, options_for_select(User::MONTHS), :include_blank => "Month:" %>
<%= f.select :year, options_for_select(User::YEAR_RANGE), :include_blank =>"Year:" %>
In my User.rb (Model) I have this validation rule and also using validates_timelessness gem:
MONTHS = ["January", 1], ["February", 2]..etc
DAYS = ["01", 1], ["02", 2], ["03", 3]..etc
START_YEAR = Time.now.year - 111
END_YEAR = Time.now.year
YEAR_RANGE = START_YEAR..END_YEAR
validates :birthday, :timeliness => {:on_or_before => lambda { Date.current }, :type => :date, :on_or_before_message => "Select a valid birthday"}
I have created some tests which work perfectly fine with the date_select that comes with rails but that date_select is buggy which is why I opted for a custom one. My only issue now is I wish to get day, month and year to work with my :birthday symbol. How do I combine all 3 so that my :birthday symbol can use the select data? If that makes sense...
The date_select would have been perfect but it lets users submit a form without the yea being filled out and if a users chooses 1 for a day and clicks submit it will automatically select january. I haven't found a way round that.
So I'm using 3 separate select fields which I want to combine and make work with :birthday just like date_select did.
Help is appreciated.
i would recommend using a date-select pop-up.
There are several gems available. I have used the one detailed in http://www.rubyinside.com/calendar-date-select-a-lightweight-prototype-based-datetime-picker-for-rails-developers-573.html with success.
Once you have a real date field you'll be in a better position to perform date type validations including ranges and presence that you can be confident in worrectly with that type of data.
The select_date isn't buggy, you need to perform the necessary data validation on your end so an empty year isn't allowed. Validation is designed to let you specify what data is allowed into your app. Only you can be the gatekeeper of what is considered 'valid'.
For a simple rails application ( 1.86 /2.3.5) , lets say I run a simple scaffold
script/generate scaffold blog title:string content:text published:date
When I open up the new / edit view for the blog controller in index/new.html.erb , I see that the drop down enabler for date select has a date range of 2005 - 2015 , i.e 5 years +/-
I tried to change this default behavior by introducing this code
f.date_select :entered,
:start_year => 1970,
:end_year => 2020
Apparently this has no impact to the behavior mentioned above. How do I increase the date_select range which seems to be default?
This seems to be ok. Except did you put it inside the <%= %> ?
Edit: Also i noticed that you say your scaffold has published column whereas your date_select refers to the entered column.
As in, <%= f.date_select :published, :start_year => 1970, :end_year => 2020 %>
If that doesn't work you can also try,
<%= f.date_select :published, :start_year => Time.now.year - 40, :end_year => Time.now.year + 10 %>
I tried it and it works for me. Cheers! :)
