In my view I have a table. This table has a <td> called 'successive_movement'
The view shows 'successive_movement' but I'd like to rename this to read 'Fast movement'.
Essentially
<td> successive_movement </td>
is displayed to the user on the view as 'successive_movement'
If possible I would like to add the <label> element to this table data in order to say 'Fast movement'.

I'm trying to run a for loop and every time a loop runs through a UIButton is allocated and initialized. The issue is that all of these buttons need different names. Is there a way to name the button based on the value of the integer in the for loop?
Is sounds like you want to put the buttons in an NSArray. Items in the array can be referenced by an index into the array.

Sorry for my English. I have a model with some field.
How to add a number to a current value in field?
I want to add the number several times
i generated scaffold.I use this to create modal. But i want to add number to a current value when i clicked submit
#foo = Foo.first
#foo.bar += 10
#which is a shorter way of saying #foo.bar = #foo.bar + 10
#foo.save
If this isn't helpful, please add some more details to your question, eg your example code you have so far.

I am trying to populate column_name with items from #enc. Problem is #update_all updates all fields with last item in array?
Last item is "MPq3KSzDzLvTeYh+h00HD+5FAgKoNksykJhzROVZWbIJ36WNoBgkSoicJ5wx\nog0g\n".
I am trying to populate with all items from array not just last.
I hope question is clear?
I tried #update_attributes, but no success?
Help.
Thanks
#enc=["hUt7ocoih//kFpgEizBowBAdxqqbGV1jkKVipVJwJnPGoPtTN16ZAJvW9tsi\n3inn\n", "wGNyaoEZ09jSg+/IclWFGAXzwz5lXLxJTUKqCFIiOy3ZXRgdwFUsNf/75R2V\nZm83\n", "MPq3KSzDzLvTeYh+h00HD+5FAgKoNksykJhzROVZWbIJ36WNoBgkSoicJ5wx\nog0g\n"]
#enc.each do |i|
PaymentMethod.update_all(enc_number: i)
end
PaymentMethod.all.each_with_index do |payment, n = 0|
payment.update_column(:enc_number, #enc[n])
n +=1
end

Hi I have a option on my web app to show the last 5 submissions. But only by the Post ID. Not by every table within the post ID if that makes sense. So when someone clicks 'recent submissions' it shows them 5 Id numbers not every single table in the id.
Post.order('created_at DESC').limit(5)
if you require only the id of the last 5 elements, then do as below:
#first_five_posts = Post.order('created_at DESC').limit(5).pluck(:id)
VIEW
<%= #first_five_posts %>

I'm trying to do a simple login form that just compare the value that you insert into the input in HTML to the data you had in the database. How can I do it?
Setup a controller and compare the params hash.
expected_value = '...'
if params[:form_value] == expected_value
do_something()
else
do_something_else()
end
