Laravel Eloquent update just if changes have been made

Question

Is there any way to update a record in Laravel using eloquent models just if a change has been made to that record  I don t want any user requesting the database for no good reason over and over  just hitting the button to save changes  I have a javascript function that enables and disables the save button according with whether something has changed in the page  but I would like to know if it s possible to make sure to do this kind of feature on the server side too  I know I can accomplish it by myself  meaning  without appealing to an internal functionality of the framework  just by checking if the record has change  but before doing it that way  I would like to know if Laravel eloquent model already takes care of that  so I don t need to re-invent the wheel   This is the way I use to update a record    product   Product  find  data  id      product- gt title    data  title     product- gt description    data  description     product- gt price    data  price      etc  string values were previously sanitized for xss attacks   product- gt save

I like to add this method  if you are using an edit form  you can use this code to save the changes in your update Request  request   id  function    post   Post  find  id        post- gt fill  request- gt input   - gt save      keep in mind that you have to name your inputs with the same column name  The fill   function will do all the work for you

You re already doing it   save   will check if something in the model has changed  If it hasn t it won t run a db query   Here s the relevant part of code in Illuminate Database Eloquent Model performUpdate   protected function performUpdate Builder  query  array  options              dirty    this- gt getDirty         if  count  dirty   gt  0                   runs update query            return true        The getDirty   method simply compares the current attributes with a copy saved in original when the model is created  This is done in the syncOriginal   method   public function   construct array  attributes   array           this- gt bootIfNotBooted          this- gt syncOriginal          this- gt fill  attributes      public function syncOriginal          this- gt original    this- gt attributes       return  this        If you want to check if the model is dirty just call isDirty     if  product- gt isDirty            changes have been made     Or if you want to check a certain attribute   if  product- gt isDirty  price            price has changed
