I try to usung devise in my rails app. But i don't understand how can i give user functionality to change his password. I need a form with fields "old password", "new password" and "new password confirmation". How can i do it? If i use default devise form on "/profile" page <%= render :template => 'devise/passwords/edit', :locals => { :resource => my_user_model_variable, :resource_name => my_user_model_name } %> In user.rb contain line attr_accessible :email, :password, :password_confirmation, :remember_me But there was undefined method 'devise_error_messages!' for #<#<Class:0x59b9200> and

I have a video file. I want to get each frame of the video and do some modifications to the frame, such as drawing another bitmap in that, putting some text etc. Is there any API/framework available to get frames from video in Android? I've done something similar in iOS using their AVFramework. If it is possible with ffmpeg, I will use some of the opensource NDKs available. Option A: You can create a SurfaceTexture object and attach this to the MediaPlayer as follows myPlayer = new MediaPlayer ... myRedirectionSurface = new Surface(mySurfaceTexture); myPlayer->setSurface(myRedirectionSurface);

Because of UI elements, I created View Controller with a TableView inside. But I can't enable editing mode. I tried several methods without Solution. But with using TableView Controller there are no problems. What I tried: override func viewDidLoad() { self.navigationItem.rightBarButtonItem = self.editButtonItem() } override func setEditing(editing: Bool, animated: Bool) { super.setEditing(editing, animated: animated) } func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) { if (editingStyle ==

I have a ListView with 3 columns and would like to edit the third column, aka Subitem[1]. If I set ListView.ReadOnly to True, it allows me to edit the caption of the selected item. Is there an easy way to do the same thing for the subitem? I would like to stay away from adding a borderless control on top that does the editing. You can Edit a subitem of the listview (in report mode) using a TEdit, a custom message and handling the OnClick event of the ListView. Try this sample Const USER_EDITLISTVIEW = WM_USER + 666; type TForm1 = class(TForm) ListView1: TListView; procedure FormCreate(Sender:

I was trying to redirect to a different page after editing an entry, I assumed that it was using the update code because you are updating the database. It took me some time to realise that I was using the wrong action in the controller. Can someone please explain how edit and update work. Why are there two different actions? what are the differences between them? edit action is responsible for rendering the view update action is responsible for interacting with the model (db updates etc) If you run rake routes you will see the difference between the verb and the action. Typically, the create

I have a gist with some javascript code in a script tag, like so: <script src="https://raw.github.com/gist/b25dff23c2c4b4bd425a/f157aa95163311c4b58febb06b49ffd16419f642/images.js"></script> And I will need to keep editing the JS file on github. However, when you edit a gist it changes the URL of the gist. How do I keep the same URL? marclundgren Gist changed the path to this file pattern: https://gist.github.com/<USER_NAME>/<GIST_ID>/raw/<GIST_REVISION_ID>/<GIST_FILE_NAME> You will notice that now the top answers' links are 404'ing. Simply apply this new pattern and voilà! https://gist.github

I need to remove the first instance of the <P> and </P> tags in multiple .htm files, all in a single directory, using a batch command. Any suggestions. Edit - I just realized that there may be multiple DIVs in the .htm files, and so I would need to remove only the 1st instance of the <P> and </P> tags in each DIV (if any). And to clarify, I only want the tags removed, but do want the content/text in between the tags to remain. Thanks for the answers/comments thus far!!! As for why, long story, but just know I work for an agency that has a contract with a vendor who did not test the version we
