# Plant Associations Implementation Plan
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
**Goal:** Ajouter des associations favorables/défavorables (plantes amies/ennemies) à chaque plante, éditables depuis la popup d'édition.
**Architecture:** Deux colonnes JSON (`associations_favorables`, `associations_defavorables`) dans le modèle `Plant` (List[str] de noms communs). Migration via migrate.py. UI tag-based avec autocomplete et validation croisée dans PlantesView.vue.
**Tech Stack:** FastAPI + SQLModel + SQLAlchemy JSON column (backend) · Vue 3 + TypeScript (frontend)
---
### Task 1: Backend — modèle Plant
**Files:**
- Modify: `backend/app/models/plant.py`
**Step 1: Ajouter les imports nécessaires**
```python
from typing import List, Optional
from sqlalchemy import Column
from sqlalchemy import JSON as SA_JSON
```
**Step 2: Ajouter les 2 champs dans la classe `Plant`**
Après le champ `notes`, avant `created_at` :
```python
associations_favorables: Optional[List[str]] = Field(
default=None,
sa_column=Column("associations_favorables", SA_JSON, nullable=True),
)
associations_defavorables: Optional[List[str]] = Field(
default=None,
sa_column=Column("associations_defavorables", SA_JSON, nullable=True),
)
```
---
### Task 2: Backend — migration
**Files:**
- Modify: `backend/app/migrate.py`
**Step 1: Ajouter les 2 colonnes dans `EXPECTED_COLUMNS["plant"]`**
```python
"plant": [
("categorie", "TEXT", None),
("hauteur_cm", "INTEGER", None),
("maladies_courantes", "TEXT", None),
("astuces_culture", "TEXT", None),
("url_reference", "TEXT", None),
("associations_favorables", "TEXT", None), # JSON list[str]
("associations_defavorables", "TEXT", None), # JSON list[str]
],
```
---
### Task 3: Frontend — interface TypeScript
**Files:**
- Modify: `frontend/src/api/plants.ts`
**Step 1: Ajouter les 2 champs à l'interface `Plant`**
```typescript
associations_favorables?: string[]
associations_defavorables?: string[]
```
---
### Task 4: Frontend — PlantesView.vue (formulaire + détail)
**Files:**
- Modify: `frontend/src/views/PlantesView.vue`
**Step 1: Étendre `form` reactive**
Dans `const form = reactive({...})` ajouter :
```typescript
associations_favorables: [] as string[],
associations_defavorables: [] as string[],
```
**Step 2: Ajouter ref pour l'autocomplete**
```typescript
const assocInput = reactive({ fav: '', def: '' })
```
**Step 3: Computed — noms de plantes disponibles pour l'autocomplete**
```typescript
const allPlantNames = computed(() =>
plantsStore.plants
.map(p => p.nom_commun)
.filter(n => n && n !== form.nom_commun)
.sort()
)
function filteredAssocSuggestions(type: 'fav' | 'def') {
const query = assocInput[type].toLowerCase()
const excluded = type === 'fav'
? new Set([...form.associations_favorables, ...form.associations_defavorables])
: new Set([...form.associations_defavorables, ...form.associations_favorables])
return allPlantNames.value
.filter(n => !excluded.has(n) && n.toLowerCase().includes(query))
.slice(0, 8)
}
function addAssoc(type: 'fav' | 'def', name: string) {
const list = type === 'fav' ? form.associations_favorables : form.associations_defavorables
const other = type === 'fav' ? form.associations_defavorables : form.associations_favorables
if (!name.trim() || list.includes(name) || other.includes(name)) return
list.push(name)
assocInput[type] = ''
}
function removeAssoc(type: 'fav' | 'def', name: string) {
const list = type === 'fav' ? form.associations_favorables : form.associations_defavorables
const idx = list.indexOf(name)
if (idx !== -1) list.splice(idx, 1)
}
```
**Step 4: `startEdit` — peupler les nouvelles listes**
```typescript
associations_favorables: [...(p.associations_favorables ?? [])],
associations_defavorables: [...(p.associations_defavorables ?? [])],
```
**Step 5: `submitPlant` — inclure les listes dans le payload**
Le spread `{ ...form }` les inclut automatiquement — rien à changer.
**Step 6: Ajouter le bloc UI dans le formulaire (pleine largeur, après les 2 colonnes existantes)**
```html
<!-- Associations — pleine largeur -->
<div class="md:col-span-2 grid grid-cols-1 md:grid-cols-2 gap-6">
<!-- Favorables -->
<div>
<label class="text-[10px] font-black text-green uppercase tracking-widest block mb-2">
🤝 Associations favorables
</label>
<div class="flex flex-wrap gap-1.5 mb-2 min-h-[28px]">
<span v-for="n in form.associations_favorables" :key="n"
class="flex items-center gap-1 bg-green/10 border border-green/40 text-green text-[11px] px-2 py-0.5 rounded-full">
{{ n }}
<button type="button" @click="removeAssoc('fav', n)" class="hover:text-red leading-none"></button>
</span>
</div>
<div class="relative">
<input v-model="assocInput.fav"
placeholder="Nom commun d'une plante..."
class="w-full bg-bg border border-bg-soft rounded-xl px-3 py-2 text-text text-sm focus:border-green outline-none"
@keydown.enter.prevent="addAssoc('fav', assocInput.fav)" />
<ul v-if="assocInput.fav && filteredAssocSuggestions('fav').length"
class="absolute z-10 mt-1 w-full bg-bg-hard border border-bg-soft rounded-xl shadow-lg overflow-hidden max-h-40 overflow-y-auto">
<li v-for="s in filteredAssocSuggestions('fav')" :key="s"
@click="addAssoc('fav', s)"
class="px-3 py-2 text-sm text-text hover:bg-green/10 hover:text-green cursor-pointer">
{{ s }}
</li>
</ul>
</div>
</div>
<!-- Défavorables -->
<div>
<label class="text-[10px] font-black text-red uppercase tracking-widest block mb-2">
⚡ Associations défavorables
</label>
<div class="flex flex-wrap gap-1.5 mb-2 min-h-[28px]">
<span v-for="n in form.associations_defavorables" :key="n"
class="flex items-center gap-1 bg-red/10 border border-red/40 text-red text-[11px] px-2 py-0.5 rounded-full">
{{ n }}
<button type="button" @click="removeAssoc('def', n)" class="hover:text-red leading-none"></button>
</span>
</div>
<div class="relative">
<input v-model="assocInput.def"
placeholder="Nom commun d'une plante..."
class="w-full bg-bg border border-bg-soft rounded-xl px-3 py-2 text-text text-sm focus:border-red outline-none"
@keydown.enter.prevent="addAssoc('def', assocInput.def)" />
<ul v-if="assocInput.def && filteredAssocSuggestions('def').length"
class="absolute z-10 mt-1 w-full bg-bg-hard border border-bg-soft rounded-xl shadow-lg overflow-hidden max-h-40 overflow-y-auto">
<li v-for="s in filteredAssocSuggestions('def')" :key="s"
@click="addAssoc('def', s)"
class="px-3 py-2 text-sm text-text hover:bg-red/10 hover:text-red cursor-pointer">
{{ s }}
</li>
</ul>
</div>
</div>
</div>
```
**Step 7: Ajouter le bloc lecture dans la modale détail (après la section Notes)**
```html
<!-- Associations -->
<div v-if="detailPlant.associations_favorables?.length || detailPlant.associations_defavorables?.length" class="space-y-3">
<h3 class="text-[10px] font-black text-text-muted uppercase tracking-widest">Associations</h3>
<div class="grid grid-cols-2 gap-4">
<div v-if="detailPlant.associations_favorables?.length">
<div class="text-[10px] font-black text-green uppercase mb-1.5">🤝 Favorables</div>
<div class="flex flex-wrap gap-1.5">
<span v-for="n in detailPlant.associations_favorables" :key="n"
class="bg-green/10 border border-green/40 text-green text-[11px] px-2 py-0.5 rounded-full">
{{ n }}
</span>
</div>
</div>
<div v-if="detailPlant.associations_defavorables?.length">
<div class="text-[10px] font-black text-red uppercase mb-1.5">⚡ À éviter</div>
<div class="flex flex-wrap gap-1.5">
<span v-for="n in detailPlant.associations_defavorables" :key="n"
class="bg-red/10 border border-red/40 text-red text-[11px] px-2 py-0.5 rounded-full">
{{ n }}
</span>
</div>
</div>
</div>
</div>
```
