I am looking to add an optional url segment in the following example:
url: "/post/:category/:subcategory/:title/{id:int}",
In this scenario, subcategory is not required. It should be able to accept:
url: "/post/sports/football/some-title/10",
as well as:
url: "/post/sports/some-title/15",
without a subcategory. I know I can achieve this using separate states, but is there a specific rule for making only the subcategory segment optional while keeping others mandatory?
.defineState('post', {
path: '/post/:category/:subcategory/:title/:{id:int}',
templateFile: 'views/post.html',
controlUnit: 'postCtrl',
parameters: {
subcategory: { collapse: true, data: null },
}
})To learn more, please visit the documentation page
Detailed explanation of the solution can be found below
Below is an example of how we can define such a parameter:
.state('state', {
url: '/:category/{subcategory:(?:football|tennis|hokey)}/:title/:id',
abstract: true,
template: '<div ui-view=""></div>',
params: {subcategory : { squash : true, value: 'football' }}
})
