Я все еще новичок в использовании Neo4j и Python.Я хочу знать, возможно ли использовать элементы списка в качестве свойств узла графа в Python и Neo4j.
Я попытался создать узел рецепта, но я получаю ошибку в переменной 'createNode'.Что я делаю неправильно?
Вот мой код:
# a list containing a list of recipes and their respective information
recipeList = [['Mac and Cheese', 'Anytime', 'Macaroni', 'Terry'], ['Chicken Curry', 'Supper', 'Chicken', 'Anne']]
def print_recipes(self,aList):
with self._driver.session() as session:
recipes = session.write_transaction(self.createRecipeNodes,aList)
print(recipes)
def createRecipeNodes(tx, aRecipeList):
for allRecipes in aRecipeList:
#for recipe in allRecipes:
recipeName = allRecipes[0]
serveTime = allRecipes[1]
mainIngrediant = allRecipes[2]
givenBy = allRecipes[3]
createNode = tx.run("CREATE (theNode:Recipe {recipeName = {recipeName}, serveTime = {serveTime}, mainIngrediant = {mainIngrediant}, givenBy = {givenBy}" ,recipeName=recipeName,serveTime=serveTime,mainIngrediant=mainIngrediant,givenBy=givenBy)
Я получаю следующую ошибку:
neo4j.exceptions.CypherSyntaxError: Invalid input '=': expected whitespace, comment, ':' or '}' (line 1, column 36 (offset: 35)) "CREATE (theNode:Recipe {recipeName = {recipeName}, serveTime = {serveTime}, mainIngrediant = {mainIngrediant}, givenBy = {givenBy}
Заранее спасибо!
