My question is: If the user wasn't logged in successfuly is there a simple way how can I add an error message to my login form? Do I have to write my own validator?

  • active_scaffold routing error

    - by Elizabeth Buckwalter
    If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works. [/Edit] ActionController::RoutingError in Departments#index Showing vendor/plugins/active_scaffold/frontends/default/views/_list_header.html.erb where line #8 raised: No route matches {:_method=:get, :action="show_search", :controller="departments"} Extracted source (around line #8): 5: <% next if controller.respond_to? link.security_method and !controller.send(link.security_method) -%> 6: <% next if link.action == 'new' && params[:nested].nil? && active_scaffold_config.list.always_show_create %> 7: <% next if link.action == 'show_search' && active_scaffold_config.list.always_show_search %> 8: <%= render_action_link(link, new_params) -%> 9: <% end -%> 10: 11: <%= loading_indicator_tag(:action => :table) %> Trace of template inclusion: vendor/plugins/active_scaffold/frontends/default/views/list.html.erb Full Trace It was taking forever to format it.

  • Index out of bounds error

    - by sprasad12
    Hello, I am working on a program where i am recreating the saved widgets back on to the boundary panel. When i am creating them i am also trying to put the values into the ArrayList so that if i want to update and save the opened project i should be able to do so by getting the values from the ArrayList. Here is how the code looks like: for(int i = 0; i < result.length; i++){ if(ename.contains(result[i].getParticipateEntityName())){ ername.add(ename.indexOf(result[i].getParticipateEntityName()), result[i].getParticipateRelatioshipName()); etotalpartial.add(ename.indexOf(result[i].getParticipateEntityName()), result[i].getTotalPartial()); }else if(wename.contains(result[i].getParticipateEntityName())){ wrname.add(wename.indexOf(result[i].getParticipateEntityName()), result[i].getParticipateRelatioshipName()); } } Here ename, ername, etotalpartial, wename and wrname are all ArrayList. This piece of code is included in an asynchronous class method. When i run the code i get error at "ername.add(ename......". Here is the error stack: java.lang.IndexOutOfBoundsException: Index: 1, Size: 0 at java.util.ArrayList.add(ArrayList.java:367) at com.e.r.d.client.ERD1$16.onSuccess(ERD1.java:898) at com.e.r.d.client.ERD1$16.onSuccess(ERD1.java:1) at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived(RequestCallbackAdapter.java:216) at com.google.gwt.http.client.Request.fireOnResponseReceived(Request.java:287) at com.google.gwt.http.client.RequestBuilder$1.onReadyStateChange(RequestBuilder.java:393) at sun.reflect.GeneratedMethodAccessor16.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessagesWhileWaitingForReturn(BrowserChannel.java:1713) at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:165) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.core.client.impl.Impl.apply(Impl.java) at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:188) at sun.reflect.GeneratedMethodAccessor9.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessages(BrowserChannel.java:1668) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:401) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:619) I am not sure what i am doing wrong.

  • Testing a Doctrine2 Entity with assertEquals results in fatal out-of-memory error

    - by Matt
    I have a PHPUnit test that's using a Doctrine2 custom repository and Doctrine Fixtures. I wanted to test that a query gave me back an expected entity from my fixture. But when I try $this->assertEquals($expectedEntity, $result);, I get Fatal error: out of memory. I'm guessing it is recursing into all the relations and the entity manager and whatnot. Is there a good way to test this equality? Should I just assertEquals on the IDs of the entities?

However, when I add the path to my .profile file and restart the terminal window, I get the same errors.
