海外TECH	DEV Community	In-place editing with Dancer2 and jQuery	https://dev.to/davorg/in-place-editing-with-dancer2-and-jquery-efd	In place editing with Dancer and jQueryI really enjoyed reading Mark Gardner s blog post about web frameworks this week but in one way it made me feel slightly sad It made me sad because it got me thinking about how a lot of Perl web development seems to be stuck in the past Oh don t get me wrong I know that modern Perl web frameworks allow you to do anything that you could do with technologies like Node js But I don t know how widely known that information is If you spend much time reading the Perl questions on Stack Overflow you ll soon realise just how much Perl web development still consists of CGI programs running in a LAMP stack For many of the people asking for help there it seems that even using a templating engine to separate your HTML from your code is cutting edge technology that they would rather avoid And that means that other modern web technologies completely pass them by But there s no need for that at all A lot of the coolest modern web technologies happen at the front end in the browser And the browser doesn t care at all what technologies you re using at the back end As long as the browser is given valid HTML CSS and Javascript to work with it doesn t matter if that was generated using Perl Node js or whatever other technology is trending this week So I thought it was worth writing a short series of articles demonstrating how you might do some clever looking modern web development tricks using Perl at the back end We ll start with in place editing of data Start with DancerI ll start with a basic Dancer application Let s pretend we re a freelance developer of some kind and we have many projects for different clients in progress at the same time At the basic level you d like to see what projects you are currently working on A useful web page might look like this Here we have two clients and there are two projects currently live for each of them This is a very basic Dancer application There are two tables called client and project I ve used Dancer Plugin DBIC to make it easy to access my database from my application There s a single route that displays this page and the page has been made to look reasonably well designed by using Bootstrap The Dancer code is trivial package APIDemo use Dancer use Dancer Plugin DBIC get gt sub template index gt title gt APIDemo clients gt schema gt resultset Client gt all true And the relevant part of the template is just a couple of simple loops lt table class table gt lt tr gt lt th gt Code lt th gt lt th gt Name lt th gt lt th gt Email lt th gt lt th gt Projects lt th gt lt tr gt lt FOR client IN clients gt lt tr gt lt td gt lt client code gt lt td gt lt td gt lt client name gt lt td gt lt td gt lt client email gt lt td gt lt td gt lt ul gt lt FOR project IN client projects gt lt li gt lt project code gt lt project name gt lt li gt lt END gt lt ul gt lt td gt lt tr gt lt END gt lt table gt In place editingSo far so good I hope But let s get a bit cleverer I m sure you ve all seen web pages where you can edit text just by clicking on the page changing the text and hitting a tick button to save your changes Let s add that feature to this page A system like this needs two components Some Javascript that gives the user an edit box when they click the text and then makes an AJAX call to a back end API to save the changesSome code at the back end that handles that AJAX call and saves the new data to the databaseLet s look at the back end first because that s the Perl bit Perl at the back endThere are a couple of approaches to this If you re a REST API purist then you ll want to write PATCH endpoints for all of the resources that can be updated in this way That s a good way to go but you can end up writing a lot of very similar code I took a different approach I wrote an API endpoint that expects to be given the type of object that is being updated because that way the same code can be used for all of your updates The code looks like this patch api update attribute gt sub my input decode json request gt content my rs schema gt resultset input gt resultset my object rs gt find input gt id if object object gt update input gt update content type application json return Note that in a production system you would probably want to keep your API in a separate application to your web site As this is a simple example they re both in the same application and I ve just used the prefix api for the API call The code isn t complicated though We expect a JSON payload which we can decode to get access to our parameters One parameter is the name of the resultset that we need to query and another is the ID of the actual object we re updating Taking those together we can use the resultset s find method to get our object from the database We expect the update parameter to be a hash mapping keys to new values that we can pass directly to the object s update method Our current example will only be updating one attribute at a time but we ve written future proof code that can handle multiple attributes at the same time The code could be cleverer Note that if we fail to find the object we just skip the update We should probably return at that point We also need to check that we re passed meaningful sets of parameters and take appropriate action if for example the resultset is missing But this is enough for a proof of concept jQuery at the front endNow it s time to look at the front end I mentioned before that the web page was designed using Bootstrap And one of the nice things about Bootstrap is that it uses jQuery for all of its front end cleverness So it s likely that a page that uses Bootstrap already loads the jQuery core library We just need to look for an add on that will support the feature that we need to add A couple of minutes with Google led me to jQuery editable which does everything we need Basically jQuery editable can be attached to any HTML element on your page The approach recommended in the documentation is to add the class editable to any elements that you want to make editable You can then use the Javascript document ready event to set up the plugin Doing this in a document ready event is a pretty standard approach when using jQuery I created a file called apidemo js which is loaded in my main layout template and which contains this document ready function editable editable function value settings var data resultset this dataset resultset id this dataset id var update update this dataset attribute value data update update var url api update attribute ajax url url type PATCH data JSON stringify data success function data console log data return value submit amp check cancel X showfn function elem elem fadeIn slow cancelcssclass btn btn danger submitcssclass btn btn success Most of this is concerned with setting up the editable function which gets called whenever the user edits the value in the HTML element We start by creating a data object that will be passed as the payload in our AJAX request The first two attributes we set up in the object are resultset and id which as we saw in the Perl code are used to find the correct database row to update We get these values from the dataset attributes attached to the current HTML element These are the data attributes that you might have seen in modern HTML You can add any attributes you like to an HTML element and the value is readable from Javascript This means that we need to alter our templates slightly so this information is added For example the lt td gt element around the client name would look like this lt td class editable data resultset Client data attribute name data id lt client id gt gt lt client name gt lt td gt We ve added the class editable so we can identify this as an editable element We ve also added the data resultset data attribute and data id attributes Some of these values are hard coded but the data id value comes from the client object that we re displaying on this row of the table So we ve put the resultset and id in the data object We then create another object that maps the attribute name to the value that is passed to the function which will be the new value of the attribute By creating a Javascript object like this we end up in the Perl code with a hash that can be passed directly to the update as we saw above We then take this update object and store it in data The next step is to make the AJAX call that actually updates the database We use JSON stringify to encode our data object into JSON so that the Perl code can decode the JSON to a Perl data structure We basically ignore the value returned from the AJAX call just writing it to the console but a more rigorous version of this code would want to look for and deal with any error responses The rest of the setup is cosmetic We set the labels for the submit and cancel buttons and use the CSS options to give the buttons classes that Bootstrap will recognise Finally we ve written a function that means the edit box will fade in slowly And that s it Save all of the files restart your Dancer app and reload it Nothing will look different but if you click on a client name you ll see this You can then edit the name and when you submit the changes they get saved to your database The nice thing about this approach is that having set it all up it s really easy to make it work for any other data item displayed on the page You just need to add the editable class and the relevant data attributes The code for this demo app is available on GitHub and in that version you can edit the client name and email address together with the project name I hope this starts to show you how you Perl can be used to build web apps that have all the bells and whistles that uses expect If there s any particular modern web feature that you d like to see me explore in this series then let me know in the comments and I ll see what I can do	2021-10-10 13:28:22
