Topic: Wrapping SideNavCat

lpokoradi priority asked 4 years ago


Hi,

I would like to create a component to group together SideNav categories, so I could render them with one condition.

<MDBSideNavNav>
    { this.state.user.roles.includes('ROLE_ADMINISTRATOR') ? <AdministratorSideNav /> : null }
...
</MDBSideNavNav>

The AdministratorSideNav component looks like:

class AdministratorSideNav extends Component {
render() {
    return [
        <MDBSideNavCat
            key='company-admin-cat'
            name="Company Administration "
            id="company-admin-cat"
            icon="chevron-right">
            <MDBSideNavItem href='/admin/location'>Locations</MDBSideNavItem>
            <MDBSideNavItem href='/admin/user'>Users</MDBSideNavItem>
            <MDBSideNavItem href='/admin/team'>Teams</MDBSideNavItem>
        </MDBSideNavCat>,
        ... more MDBSideNavCat
    ];
}};

The rendering looks okay. The only problem is that clicking is not working. Clicking on the MDBSideNavCat (Company Administration in my example) only results in the ripple effect, but the category is not opening.

Is there any trick I am missing?

Regards, Laszlo

Did you try to put all URL address into href?


lpokoradi priority commented 4 years ago

Sorry, but I don't get it. What do you mean "put all URL address into href"?


Piotr Glejzer staff commented 4 years ago

Oh sorry, I thought about a different problem.

So, did you try to use props isOpen?


lpokoradi priority commented 4 years ago

If I change the value of isOpen from false to true, in the React DevTools, yes the category opens as it should. But the question why it is not working.


lpokoradi priority commented 4 years ago

I would create a snippet for you, but "Something bad happened during initialization ;("


Piotr Glejzer staff commented 4 years ago

You can copy and paste all code here, I will check

Hi Piotr,

Thanks for the reply, I already knew that workaround is working, but it doesn't help me to have clean code.

So will it be possible decoupling like I would like to?


Piotr Glejzer staff commented 4 years ago

Is not possible to do it without duplicated a code. I added task to fix this. Sorry about that.

Ok, I figured it out.

So the main problem is that our component SideNavNav has a React.Children method on what type of component name is returning and it if is a SideNavCat return a React.cloneElement with prop onClick and isOpen what number is clicked and what component is open at the moment.

If you are returning elements like that:

    {this.state.user.roles.includes('ROLE_ADMINISTRATOR') ? (
      <>
        <MDBSideNavCat
          key='company-admin-cat'
          name='Company Administration '
          id='company-admin-cat'
          icon='chevron-right'
        >
          <MDBSideNavItem href='/admin/location'>Locations</MDBSideNavItem>
          <MDBSideNavItem href='/admin/user'>Users</MDBSideNavItem>
          <MDBSideNavItem href='/admin/team'>Teams</MDBSideNavItem>
        </MDBSideNavCat>
        <MDBSideNavCat
          key='assessment-admin-cat'
          name='Assessment Administration '
          id='assessment-admin-cat'
          icon='chevron-right'
          isOpenID='3'
        >
          <MDBSideNavItem href='test'>Submit listing</MDBSideNavItem>
          <MDBSideNavItem>Registration form</MDBSideNavItem>
        </MDBSideNavCat>{' '}
      </>
    ) : null}

It is not working as I said because the first displayName is a react.fragment instead SideNavCat.

The solution for that is to split the above condition to separate objects. Like this:

   {this.state.user.roles.includes('ROLE_ADMINISTRATOR') ? (
      <MDBSideNavCat
        key='assessment-admin-cat'
        name='Assessment Administration '
        id='assessment-admin-cat'
        icon='chevron-right'
        isOpenID='3'
      >
        <MDBSideNavItem href='test'>Submit listing</MDBSideNavItem>
        <MDBSideNavItem>Registration form</MDBSideNavItem>
      </MDBSideNavCat>
    ) : null}

    {this.state.user.roles.includes('ROLE_ADMINISTRATOR') ? (
      <MDBSideNavCat
        key='company-admin-cat'
        name='Company Administration '
        id='company-admin-cat'
        icon='chevron-right'
      >
        <MDBSideNavItem href='/admin/location'>Locations</MDBSideNavItem>
        <MDBSideNavItem href='/admin/user'>Users</MDBSideNavItem>
        <MDBSideNavItem href='/admin/team'>Teams</MDBSideNavItem>
      </MDBSideNavCat>
    ) : null}

    this.state = {

      user: {
        roles: ["ROLE_USER", "ROLE_ADMINISTRATOR", "ROLE_DELIVERY"]
      }
    };
  }

  handleToggleClickA = () => {
    this.setState({
      isSideBarShown: !this.state.isSideBarShown
    });
  };

  render() {

The "Submit blog" SideNavCat is working perfectly, but my AdministratorSideNav component is just rendered correctly, but the click event is not opening the category.
