Rails list records for a particular day

Question

I'm trying to create an index.html.erb file that will list records from a table called events. I'm trying to select records for a particular day. starts_at is a datetime field in the table. For example, I'm trying to get all of the records for Monday of this week using:

<% @events = Event.where('starts_at.to_date = ?', DateTime.now.beginning_of_week.to_date) each do |event| %>

But, I don't get records when I should.

One thing it doesn't like is the each statement.

Thanks in advance for the help!

Answer 1

我相信您缺少等号条件符号。

<% @events = Event.where('starts_at.to_date = ?', DateTime.now.beginning_of_week.to_date) each do |event| %>

Answer 2

You can use AREL.

@date = DateTime.now.beginning_of_week
@events = Event.where(starts_at: @date..@date.end_of_day)

And that should go in your controller. It's not recommended to do DB queries in your view (not very MVC!).

Answer 3

Event.find(:all, :conditions => ["DATE(starts_at) = DATE(?)", DateTime.now.beginning_of_week])

要么

Event.where("DATE(starts_at) = DATE(?)", DateTime.now.beginning_of_week)
