rails 4.2 link_to method: No route matches [POST] -

-

i'm trying construct link_to method: :delete call destroy method in users controller:

<%= link_to 'disable token', user_path(user), method: :delete, data: { confirm: 'are sure?'} %>

which generates html looks like:

<a data-confirm="are sure?" rel="nofollow" data-method="delete" href="/users/6">disable token</a>

my application.js file has:

//= require jquery                                                                                                                                             //= require jquery_ujs

and, in fact, know javascript loaded , doing supposed to, because generates 'are sure?` alert dialog.

however, when following link following:

no route matches [post] "/users/9"

and indeed there no such route, because routes are:

users_path  /users(.:format)    users#index user_path   delete  /users/:id(.:format)    users#destroy

the mystery (to me) why rails doing post route in first place? you'll note url correct ("/users/9") http verb not: post.

the parameters of request getting set:

{"_method"=>"delete",  "authenticity_token"=>"vcavjf1/f9mwjni4gptertdiyjkobniof0hiqvf+3bvmzuniohymm2z3w2sqsljqj11sz/tiht78aa9 }

here can see _method key being set delete should be, why routing error?!?

i'm stumped.

edit: if change link_to call include remote: true rails routes proper route! so, "fix" i've changed controller use ujs, don't because, well, far can tell had before should work!

here link_to call sends proper delete request js:

<%= link_to 'disable token', u, method: :delete, data: { confirm: 'are sure?'}, remote: true %>

just try explicitly stating controller action , method (note @user.id example, may referencing differently) url_for:

<%= link_to 'disable token', url_for(action: :destroy, id: @user.id), method: :delete, data: { confirm: 'are sure?'} %>

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...
