Condition avant la boucle

Bonjour,

Pourquoi dans mon code

def index
   rtCriteria = ""
session[:list_search_criteria] = Hash.new if
session[:list_search_criteria] != ""

session[:list_search_criteria]["#{params[:criteria]}"] =
params[:criteria_texte] #unless params[:criteria_texte].blank?

session[:list_search_criteria].each {|key,value| rtCriteria = "
profiles.#{key} = '#{value}'" }

     if rtCriteria.blank?
       puts rtCriteria
     else
        #actions 1
end

La condition se lance avant la boucle

Merci

Sorry folks, I'll just tell Bolo to take this OL or switch language!

Bolo tu es sur une liste de courriel anglais.
Si tu hésites de écrir en Anglais tu peux m'envoyer ça sans problème.
Si tu es alais en Anglais restes ici c'est une liste formidable.

Pour ce qui concerne ton problème j'ai un petit peu mal à comprendre
ce que ce code devrait faire, la method ne peut pas fonctionner comme
ça, (c'est Rails? dans ce cas la liste de courriels serait encore une
autre).
session et params ne sont définit nul part, mais je devine un petit peu:

Ne voudrais-tu pas écrire
session[:list_search_criteria] ||= Hash.new
ou à la limite
session[:list_search_criteria] = Hash.new unless
     session[:list_search_criteria] && ! session[:list_search_criteria].empty?

session[:list_search_criteria][params[:criteria].to_s] =
  params[:criteria_texte] #unless params[:criteria_texte].blank?

  session[:list_search_criteria].each {|key,value| rtCriteria = "
profiles.#{key} = '#{value}'" }
Attention rtCriteria n'a que la dernière valeur, je propose que tu ecrives
rtCriteria << "..."

if rtCriteria.blank?
  puts rtCriteria
else
  #actions 1
end

le puts émet toujours "", le sais-tu bien?

N'hésites pas à précisier tes questions Off List.

I am apologize, I wrote my question in French

My problem is why i did something like

···

************************
array = {:bolo => "toto" , :bolo => "toto" }
array.each {|key,value| rtCriteria = "#{key} = '#{value}'" }
if rtCriteria.blank?
  puts "rtCriteria is ok"
else
puts "rtCriteria is not "ok
end
**************
I have always
rtCriteria is not ok

the if method was called before the each method

It's more clear ?

Oops sorry wrong button

I am apologize, I wrote my question in French

************************

Assuming:

rtCriteria = ""

array = {:bolo => "toto" , :bolo => "toto" }

Actually array is a hash and it has only one pair of values :bolo => "toto"

array.each {|key,value| rtCriteria = "#{key} = '#{value}'" }

You will habe rtCriteria ="bolo = 'toto'" and not blank?, but blank?
is not Ruby, I believe it is defined somewere in the Rails libraries.
In Ruby you can use rtCriteria.strip.empty? I believe.

if rtCriteria.blank?

As I said above rtCriteria is not blank it's value = "bolo = 'toto'"

  puts "rtCriteria is ok"
else
puts "rtCriteria is not "ok
end
**************
I have always
rtCriteria is not ok

the if method was called before the each method

It was not, if it were rtCretieria might be blank indeed!

It's more clear ?

Yes and now, I know what is wrong in your code but I do not know what you want.
You probably want a string like this
"bolo => 'toto', robert => 'titi'" for a hash.
In that case try this

result =""
{:bolo => 'toto', :robert => 'titi'}.each{|k,v| result<< ", #{k} = '#{v}'"}
result[2..-1]

The *Ruby* way might be to use inject though
{:bolo => 'toto', :robert => 'titi'}.inject(){|a,(k,v)| a << "#{k} =
'#{v}'"}.join(", ")

If it is something else you want to achieve just tell us what the
exact result should be.

Cheers
Robert

Hello,

Yes and now, I know what is wrong in your code but I do not know what you want.

I would like to generate a hash for the condition in my finder

a["profiles.name"] = "bolo"
a["profiles.age"] = "25"

Thanks for the tips
a.inject(){|rtCriteria,(k,v)| rtCriteria << "#{k} ='#{v}'"}.join(",
")

irb(main):017:0> puts rtCriteria
profiles.age ='25'
profiles.band ='bolo'
=> nil
irb(main):018:0>

The only problem i have. I would like something like that
profiles.age ='25' AND profiles.band ='bolo'

Can you help me again ?

Thanks
