My before_save doesn't update the verified_date field.
Why is that? Other processes can update the field ok.
Model:
class Link < ActiveRecord::Base
belongs_to :group
validates_presence_of :url_address
validates_presence_of :group_id
validates_size_of :version_number, :maximum => 10 #, :allow_nil => true
before_save :verify_this_link
acts_as_list
...
def verify_this_link
verified_date = Time.now
end
end

I want to manage the rates of a product in multi-currency and keep historic of currency rates.
So onetomany relation:
A Rates can have many CurrencyRate.
A manyto many relation:
Many currencyRate have many currencies.
RATES :

+-------------+--------------+------+-----+---------+----------------+
I want to generate a form from all of this.
The html form would get all available currencies with a text field to indicate the CurrencyRate.
Ex :
USD <input type="text">
EUR <input type="text">
CNY <input type="text">
...
I saw the documentation on Symfony about manytomany form. But mine is more complex with an additional onetomany relation and text field. I am totaly lost.
Thanks if you can put me on the right direction.
Best regards,
Pierre
I found the response :
First I needed to correct my Schema which didn't need a ManytoMany relation :
Rates :

CURRENCY RATES

| Field | Type | Null | Key | Default | Extra |
+-------------+---------+------+-----+---------+----------------+

Then One Form Type
class CurrencyRateType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('currency',EntityType::class, array(
'class'=>'AppBundle:Currencies',
'choice_label' => 'abreviation',
'disabled' => true,
))
->add('ratio', TextType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => CurrencyRates::class,
));
}
}
which is embedded in the final form type :
class RateType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder ->add('rate')
->add('CurrencyRate', CollectionType::class, array(
'entry_type' => CurrencyRateType::class,
'entry_options' => array('label' => false))
)
->add('save', SubmitType::class, array('label' => 'create'));
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => Rates::class,
));
}
}
How can I get the first name and last name from the table User through table Friend which is referenced by the user_id with the condition of user_id 5 and status is pending and place it in a each loop but i also need the contents of friend controller in rails. Thank a lot for the help
Controller
#add = Friend.where(user_id: 5, status: 'Pending')
User Database
+-----------------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------------+--------------+------+-----+---------+----------------+
| id | int | NO | PRI | NULL | auto_increment |
| first_name | text | YES | | NULL | |
| last_name | text | YES | | NULL | |
| email | text | YES | | NULL | |
| contact_number | varchar | YES | | NULL | |
| birth_date | date | YES | | NULL | |
| created_at | datetime | NO | | NULL | |
| updated_at | datetime | NO | | NULL | |
Friend
+--------------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------------+--------------+------+-----+---------+----------------+
| id | int | NO | PRI | NULL | auto_increment |
| request_date | date | YES | | NULL | |
| reason | text | YES | | NULL | |
| status | varchar(255) | YES | | NULL | |
| userid | int | YES | MUL | NULL | |
How about this:
#add = Friend.joins(:user).select("users.first_name, users.last_name").where(user_id: 5, status: 'Pending')
Seems like youre already fetching the id of the user, stored in the user_id field. In order to get the associated user, i would do
#user = User.find(#add.id)
This retrieves the user based on the id you pass, and from there you can do stuff like
#user.first_name
to get the values
All you need to do in Friend model belongs_to user and then
#add =Friend.where("user_id = ? AND status = ?", 5,"Pending")
and
<#add.each do |s|>
<%s.user.first_name%>
<%=<%s.user.last_name%>
// and so on..
<%end%>
If I in Google Sheets have a series defined as

29342, 29372, 29373].
How do I make them line up in intervals like this?
|To |From |

29342, 29372, 29373
B1: =transpose(split(A1,",")). Converts the input text is an a vertical array.
C1: =FILTER(B1:B16,mod(ROW(B1:B16),2)<>0). Returns values in odd rows.
D1: =FILTER(B1:B16,mod(ROW(B1:B16),2)=0). Returns values in even rows.
E1: =ArrayFormula(FILTER(C1:C8,{TRUE();C2:C8<>D1:D7+1})). Returns values that start a range.
F1: =ArrayFormula(FILTER(D1:D8,{D1:D7+2<>D2:D8;TRUE()})). Returns values that end a range.

What would be a good approach to report of all the dates a name occurs in a list? Can this be done with a single array formula?
Example (column A and B are input, columns C through G are to be auto-generated):
| A | B | C | D | E | F | G |
+---------+--------+--------+---------+---------+---------+---------+
| Episode | Stars | Name | Date | Date | Date | Date |
+---------+--------+--------+---------+---------+---------+---------+
| 7/24/15 | Bart | Bart | 7/24/15 | 7/18/15 | 8/15/15 | 3/29/15 |
| 8/09/15 | Maggie | Homer | 1/10/15 | | | |
| 7/24/15 | Marge | Lisa | 7/20/15 | 6/04/15 | | |
| 7/18/15 | Bart | Maggie | 8/09/15 | | | |
| 1/10/15 | Homer | Marge | 7/24/15 | | | |

I don't think this is easily possible in a single arrayformula. However, as an alternative you could try this formula in cell C2:
=SORT(UNIQUE(QUERY(FILTER(B$2:B,LEN(B$2:B)))),1,1)
Then try this formula in cell D2 and drag down:
=TRANSPOSE(QUERY(A$2:B,"select A where B='"&C2&"'"))
See this example sheet to see it working: https://goo.gl/0u41u5

As you can see from po commands, I am getting NSAutoresizingMasktLayoutContraints. I thought this shouldn't happen?
How can I ensure that I don't get this?
Ok.. I have figured out that the constraints did not appropriately address the relationship between each other. I have updated the code and now I can get clean constraints for all aspects, except for the main UIWindow, which I am sure is just because of the problem with the UILayoutGuide being ambiguous -

The UILayoutGuide is not set anywhere in my code, so I am not quite sure what do with it.
