Thanks for sending so much of your code. Does |

Nope, even by setting the function as an empty one with only Sure CategoryView from django_unicorn.components import UnicornView
from trouve_ton_meme.models import Category, Meme
class CategoryView(UnicornView):
categories = Category.objects.none()
modal_meme = Meme.objects.none()
def mount(self):
self.categories = [Category.objects.get(id=self.request.GET.get('id'))]Full trace of the error |

@adamghill Do you have any solution for this ? |

@gschurck Unfortunately, I haven't been able to replicate this on my own. The last line is in |

Hello adamghill, I think I might have a similiar issue, but cannot provide a full example currently. <a unicorn:click.prevent="select_item()" href="#">Click</a><!-- mdb-index-info-details-parent.html -->
{% load unicorn %}
<div class="row">
<div class="col-lg-4">
{% unicorn 'mdb-index-info-details-items' %}
</div>
<div class="col-lg-8">
{% unicorn 'mdb-index-info-details-chart' %}
</div>
</div>MdbIndexInfoDetailsItemsView and MdbIndexInfoDetailsChartView are childs of MdbIndexInfoDetailsParentView I noticed that the error disappeared when I removed one of the childs from parent template. |

I think this should be fixed by 0.58.0 of |

I ran into a similar problem. After some digging I was able to set a breakpoint into the faulty callstack:
Turned out that django_redis, uses beautifulsoup4 for serialization, and bs4 relies on some hardcoded delimiter name "Tag": My problem was that my component view contained a variable for a model named Tag, which was serialized as is, without any escaping. This made the whole parsing fail :-O |

@philippe-docourt Thanks for debugging this and figuring out the callstack that triggered it. Any idea of how to stop it from happening? |
There is a Recursion Error with my website.
RecursionError: maximum recursion depth exceeded while calling a Python objectI use a view with a loop that call multiple children
category.html
{% extends 'base.html' %} {% block content %} {% load bulma_tags %} {% load unicorn %} {% load static %} <div class="container" unicorn:view> <h1 class="is-1 is-size-1-desktop is-size-3-mobile has-text-centered mb-6">Catégorie</h1> <div class="level" id="ttm-loader"> <div class="level-item"> <img src="{% static 'monkaS.png' %}" class="loader"> </div> </div> <div id="loading-images"> {% for category in categories %} <h2 class="is-2 is-size-3-desktop is-size-4-mobile is-underlined has-text-centered my-5">{{ category.name }}</h2> <div class="columns is-multiline is-mobile is-variable is-1-touch"> {% for meme in category.get_memes %} <div class="column is-one-quarter-desktop is-half-touch"> {% unicorn 'meme_card' parent=view meme=meme key=meme.id id=meme.id %} {# parent=view #} </div> {% endfor %} </div> {% endfor %} </div> {% unicorn 'meme_card_modal' %} </div> {% include 'loader.html' %} {% endblock %}Children :

meme_card.py
from django_unicorn.components import UnicornView from trouve_ton_meme.models import Meme class MemeCardView(UnicornView): meme = Meme.objects.none() def set_meme_modal(self, meme_id): print(self.parent) meme = Meme.objects.get(id=meme_id) self.parent.modal_meme = memeThe function is executed and I have access to the parent, but it crashes after that with a RecursionError from Django unicorn.
I don't really understand where is the recursion here.
Is there any solution for this ?
