I want to implement a feature in Rails using the option of multiple checkbox. User must be able to choose the days in which he want the emails, like Monday, Tuesday, etc. This must be a list of checkboxes with day name as label and day index like 0 for Sunday, 1 for Monday, like that.
Also these fields must be checked when the user next time come here to edit.
I don't want to create separate db field for each day. This can be an array of day index stored in one database field. I am using Rails version 4.
Date::DAYNAMES will give the list of week days. Date::DAYNAMES.each_with_index will give the list of days with its index. I want to know the best way to implement the same.
Try this,
<%=select_tag 'days[]', options_for_select(Date::DAYNAMES.zip((0..6).to_a),
[selected days array goes here]
), :multiple => true%>
For using checkbox
<ul>
<% Date::DAYNAMES.zip((0..6).to_a).each do |day| %>
<li>
<%= check_box_tag 'days[]', day[1], [selected days array].include?(day[1]) -%>
<%= h day[0] -%>
</li>
<% end %>
</ul>
Hope it's help you.

I am building a search engine that selects a User (model), the month (created_at column), year (created_at column) and their Posts (model). Each post has three integer columns. I need to know how to get the total (sum) for each week of the month for these three columns, for the specified user. I will iterate over each week and show the totals underneath the week. How can you do this in rails? I know the cweek attribute gives you the real number for the current week. But, how would I track that information if I use params[:month], params[:year]?
Week container
<% #user.posts.week.with_index(1) do |week, index| %>
<p>Week <%= index %></p>
<%= week.total %>
<% end %>
I'm stuck on a tiny problem regarding chartkick. I have a rail app where you can create different currencies. You can then create a expense with a title, a amount and choose the currency from a list and the user_id. The relations are made and working. I have in my user controller something like this :
#user_spendings = #current_user.spendings.all.order('date DESC').paginate(:page => params[:page], :per_page => 15)
#sums_by_currency = Currency.joins(:spendings).
select(:symb, 'SUM(spendings.amount) AS amount').
where(spendings: { id: #user_spendings.map(&:id) }).
group(:symb)
And in my show view (as I want the expense from each user to be shown there) something like this :
<% #sums_by_currency.each do |currency| %>
<%= '%.02f' % "#{currency.amount}" %> <%= "#{currency.symb}" %>
<% end %>
That shows me the sum for each spending depending on the currency.
I would like to use this total and use chartkick to display the spending, with the date when this spending has been created.
I've tried several things already
First I went with this just to see :
<% #sums_by_currency.each do |currency| %>
<%= bar_chart currency.amount %>
<% end %>
Well I have to charts appearing but nothing shows up. Maybe the loop isn't the solution. Then I thought about the .map but I don't really know how to put that in place to be honnest.
I tried this aswell :
<%= line_chart #current_user.spendings.group(:date).sum(:amount) %>
That shows me the total spendings from all the currencies. I have to find out how to split all the currencies in different charts and show only the total amount from each currency.
If anyone can give me a clue I would appreciate it.
Thanks alot.
Ok guys I got it !
Took me 2 days only...
For the one interested in the answer here is what I did. I actually didn't change anything in the controller and I let the #sums_by_currency like it is.
Instead I went for that :
<%= column_chart #current_user.spendings.all.joins(:currency).group('currencies.symb').group_by_month(:date, format: "%B %Y").sum(:amount) %>
Give me all the spendings from the current_user from where I joined the currency that I grouped by symb. Then I grouped everything by month and I get the sum from the amount.
Yeah, you need to pass a set of data to the chart, not lots of individual pieces of data for individual charts (ie what you've got with the loop). Using map to convert your currency-objects to their amounts makes sense eg
<%= bar_chart #sums_by_currency.map{|c| c.amount } %>
or if you need a name something like:
<%= bar_chart #sums_by_currency.map{|c| {name: c.unit, data: c.amount} } %>
Where unit is whatever currency unit eg AUD
I am in the process of creating an competition app that needs to be pretty much autonomous. The app has a resource called 'Weeks' and each week has many 'Entries'. Users can add an entry to the week, and then they can be voted on.
The week has a database column called 'start_date' and if I populate this with a string, eg "16-03-2015" then on the Show view I can pull in the weeks params and compare the string to todays date and set whether the vote buttons are active or not.
In my weeks controller I use a before action called set_dates and I set a couple of variables
def set_dates
#today = Date.today
#weekstart = Date.parse(#week.active_date)
#weekend = Date.parse(#week.active_date)+7
end
I can then set if and else statements on the view to show the vote buttons if the week is 'active', ie. todays date is within the active_date + 7 days
<% #entries.each do |entry| %>
<div class="entry">
<%= image_tag(entry.photo(:thumb)) %>
<%= entry.cached_votes_up %>
<% if (#weekstart..#weekend).include? #today %>
<%= link_to "Upvote", upvote_week_entry_path(entry.week_id, entry) %>
<%= link_to "Downvote", downvote_week_entry_path(entry.week_id, entry) %>
<% end %>
</div>
<% end %>
This was fine until I realised I needed to have an 'active week' outside of the show view. I want to put a link into the Navigation Bar in the application_layout to 'This Weeks Comp', and I need this week to point to whichever week voting is active on. But without finding the week by its ID, then cross referencing it's active_date, I am unsure how to do this. Any help would be greatly appreciated.
Thanks!
If anyone else is find this looking to solve a similar problem, I solved the issue by adding an end_date column to the weeks resource, and then assigned a variable to an arel query in the application controller
App-Controller
before_action :active_week
protected
def active_week
#aweek = Week.where("? BETWEEN start_date AND end_date", Date.today)
#active = #aweek.first
end
Application Layout
<%= link_to "This Week", #active %>
I have a calendaring application I am working on in Rails 3. I am gathering a 'to' and 'from' date from the user and creating a date, and creating events based on that range. Here is the code:
date_range = (params[:from_date]..params[:to_date]).to_a
date_range.each do |r|
params[:orientation][:class_date] = r
#orientation = Orientation.new(params[:orientation])
#orientation.save
end
This works like a charm. Now I want to add check boxes in the view for Monday - Friday so the user can specify which days the want a repeating event to be created for. My thinking is to expand on the logic above and create a date range with the 'to' and 'from' dates, then remove dates based on check boxes (days) the user checks. If the user checks 'Mon', 'Wed', 'Fri', I would create my date range, then remove all Thursday and Friday dates from the range. Can anyone suggest any methods in Ruby that might be handy for dealing with this?
You could add checkboxes in your form to ignore the selected date and then ignore each day in the loop:
# view
<% Date::DAYNAMES.each_with_index do |day_name, wday| %>
<%= check_box_tag "ignored_days[]", wday %>
<%= day_name %>
<% end %>
# controller
date_range.each do |r|
next if params[:ignored_days].include? r.wday.to_s #added edit here
params[:orientation][:class_date] = r
#orientation = Orientation.new(params[:orientation])
#orientation.save
end
Hope this helps!
I'm using a date select in a rails 3 form.
<%=f.date_select :date %>
I would like to restrict the dates so that you can only pick dates that fall on a Sunday. Is there any way of going about doing this?
I'm also trying to stop dates which have already passed from appearing.
Thanks for any help in advance!
Rails date_select field generates three dropdown to select the parts of the date. There is no chanche, that you modify for example the month, and the day will still be sunday.
You must write some js magic to enforce such a role, or find an already existing datepicker and limit it. Or alternatively, you let the user to select a week, and calculate the exact date of sunday from that.
Ok having studied this out a bit further I don't think this is possible due to the format of the date_select field. The closest I can get is
<%=f.date_select :date, start_year: Time.now.year %>
so that at least you can't select dates from previous years. I've implemented the restriction on days and months that have past by setting up the view to automatically delete records that aren't relevant:
<% if(service.date < Date.today) %>
<% service.destroy %>
<% end %>
Not perfect but does the job in my case.
