preventing exceptions in rendering a timeline element

[smarques]

Hi, I have a complex range of timeline elements with different data structures so its possible that sooner or later something breaks and I get an exception that blows up the entire timeline if it gets raised within the tig call 'timeline_render'. What would be the best way to achieve the following behaviour from timeline render (de facto its a try and catch):

• if the rendering of one element fails just ignore this element and go on to render the remaining timeline elements.

Thanks so much for any help sergio

Hi,

timeline_render behavior is simple. You have documentation here

• First of ALL, it search for a verb twig file. Fallback is here

Your verb file looks like to something like that:

{{ timeline_component_render(timeline,'subject') }} eat with {{ timeline_component_render(timeline,'directComplement') }}

Here, you see the usage of timeline_component_render. By default, it call the __toString method of object or use string. You are able to uses components to customize the render of yours object/verbs.

Where would you have an exception ?

If it's on the verb file, you should use twig asserters because timeline bundle cannot do anything.

{% if action.hasComponent('directComplement') %}
.........
{% endif %}

If it's because integrity of complements is not sure, you should look at DataHydrator filter and its option to remove unloaded components

I hope i answered to your questions.

Thank you for your reply. Yes its related to the integrity of components. Will look at the dataHydrator filter. Thanks for pointing me to the solution :) :+1:
