Guide to resetting all ReactiveVars to false in Meteor JS

I am currently working on a recipe template where I am using {{#each recipes}} to render the recipes. I have implemented ReactiveVar to toggle the edit form of each recipe from hide to show. Everything is functioning correctly, but I want to ensure that when I click the edit button for one recipe, all other open recipe forms are set to hide.

Template.Recipe.onCreated(function(){
        this.editMode = new ReactiveVar(false);
    });

Template.Recipe.helpers({
    editMode: function() {
        return Template.instance().editMode.get();
    }
});

Template.Recipe.events({
    'click .fa-pencil': function(event, template) {
        //I need to include something here to reset all other "editMode" variables to false
        template.editMode.set(!template.editMode.get());
    },
});

Answer №1

Perhaps a new strategy is in order

Consider implementing a Session variable that stores the Id of the recipe currently being edited, then utilize a template helper to determine if the current recipe is the one under editing

Add a property to each recipe indicating whether it is being edited or not; remember to update the collection when you switch between edited recipes

Create a common object with a reactive variable using a similar approach as the Session variable. If applicable, place this functionality within a parent template for optimal organization (the most elegant solution)

Answer №2

To achieve the desired functionality, it is important to consider how the templates interact with each other. Each template should not have the ability to dictate the state of its siblings, indicating a flawed approach.

The recommended approach is to store the state in a global location accessible to all templates for seamless interaction and reaction. This can be achieved through Session (as previously suggested) or using a route parameter (which I find to be a better solution).

Alternatively, utilizing the parent component to manage and share data among its children by employing events for communication is another viable option. This enables a child template to send an event to the parent, which can then relay the message to other children components efficiently.
