ruby - Overwriting #each; can I pass it args through #map, #select, etc? -


I have written my own tree class which contains anonymous tree then returns a # iH function. As a result, it automatically receives numeric functions like #map , #select , #find

Here's the problem when I wrote for #each my tree , I gave a code which is # iH Is an argument used by the name of the tree traversell algorithm, such as : pre_order or : breadth_first . But now when I #map or #inject or #any? et, it can only use the default traversal algorithm, is there any way that I can pass this argument through another innovative function? Here are my criteria;

  • I should be able to use any traversal algorithm for any numerical function. It is very important because different algorithms for trees are very different Can be demonstrated.
  • I do not want to rewrite each single numerical function to pass this argument to #each ; Which defeats the purpose of the module.

    This is a short version of my code; 

      are included in the class tree ... # overwrite #hash, and make it algorithmic argument. DRF Each (Algorithm =: Pre_Order, and Block) if TravelWill_Algorithms are included in this? Algorithms self.send (algorithm, and block) other self.method_missing (algorithm) end-end pre-order (& amp; block) sub-self.branches.each Branch; Branch.pre_order (& amp; block) end-end def post_order (& block) ... end def fourth_ & nbsp; (& Amp; Block) ... and end   
     I want to call things like this;  
      tree.find (13, breadth_first) tree.any? (: Post_order) do | Node | node.root & gt; = 10 end    
     
     
     I'm pretty stupid.  
     The method  #enum_for  gives me all the power here by adding the traditional line  
      tree.breadth_first.find (13)   
     Apply the syntax of Charlie  
      Change to self.enum_for (__ method__) until block_life is not there?  tree.breadth_first  will return a  calculator   
     in each of my traversal ways that calculates the width according to the algorithm first; Any  enforced  method will be used internally for that calculation.

c# - ASP.NET MVC - Attaching an entity of type 'MODELNAME' failed because another entity of the same type already has the same primary key value -

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.

django - CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False -

I use Django 1.6.5 with settings in my program txsite: DEBUG = true I set the lie to debug, but when I get the runner , I get the following error: CommandError: You have to set the settings. OLOWOWHESTS If DEBUG is False I ALLOWED_HOSTS = ['127.0.0.1', 'localhost'] but I get the same error. Does anyone know this address? Try ALLOWED_HOSTS = ['*'] Less secure If you are not on a firewall or public LAN, but what I use and it works. Edit: Interestingly enough, I have to add some of my 1.8 projects, even if DEBUG = True . Why so very uncertain
