As a Neo4j Bloom user, I want to easily upload custom icons for nodes so that I am not limited to the defaults. Acceptance Criteria: Users should be able to upload custom icons for Neo4j Bloom nodes. Ideally, the supported filetypes would be .PNG and .SVG. The required size / ratio for custom icons should be visible to users. Ideally, Neo4j would be able to upscale / downscale .SVG icons gracefully for beautiful rendering. ... View more

In this tutorial: Neo4j Graph Database Platform Creating Relationships - Introduction to Neo4j 4.x Series There is the query: MATCH (a:Person), (m:Movie) WHERE a.name = 'Michael Caine' AND m.title = 'Batman Begins' CREATE (a)-[:ACTED_IN]->(m) RETURN a, m with an explanation that this query will create a cartesian product but it does NOT explain how to avoid that! Avoiding a cartesian product is explained here: Avoid cartesian product when create relationships Cypher Hi! I'm new to neo4j and I try to find some help here. I have two sets of nodes say one is people and another is car.I want to create relationship between these two sets of nodes but I don't want to create relationships base on cartesian product of result return by match since it will take much time. The cypher statement I use like below: MATCH (a:test_11),(b:test_12) WHERE a.car ="0" AND b."price" = "1" MERGE (a)-[r:own{time:2020,location:"LA"}]->(b) Is there a way to write cyher which ca… (I would have made a Pull Request on it, but I don't know where it lives in github.) ...

Hello. I read the graphql doc and find there isn't exist mutation of upsert(or createOrUpdate) which is very useful in batch update, it has been implemented by Dgraph. https://dgraph.io/docs/graphql/mutations/upsert/ I only find connectOrCreate which can create or connect the node, but don't offer hook to UPDATE the property's value of match(connect) node. Say we have a schema type Product { id: ID @id name: String hsCode: String price: Currenty @relationship(type: "HAS_PRICE", direction: OUT) } type Currenty { id: ID @id currencyCode: CurrencyCode @default(value: USD) amount: Float! } enum CurrencyCode { "US Dollar" USD "EURO Currency " EUR "Japan Yuan" JPY "Hongkong Dollar" HKD "China Yuan" CNY #ISO 4217 } I want to update the name of Product and amount of price within same mutation. Sometime we will offer price when create product, but something not. So when I want to update price of product, there maybe has not price(type: Currency). What I expected is when the price is not exsisted(determined by id), it will created a new one, if the price's id exist, it will update the node with the given data within some method such as onUpdate or onCreateOrUpdate... mutation xx{ updateProducts( where:{id:"***"} update:{ name: "Foobar" price:{ connectOrCreate:{ // I want another upsert operation here where:{id:"**"} onCreate // It should have onConnect hook too. So we can update the node here, such as onConnect { node: { name: "Product A" } }, we will match the node and UPDATED at the same time here. // if will have onCreateOrUpdate hook here, it will be great, I will update or create from given data without considering which type(create or connect) of mutation it take. } } } ) } So I was stuck now, I can't update the price if the id exist. I have to write another Mutation to do this task. So I have two Mutation for nested update, also I have to judge if the price's id(type Currency) is exisit before I decide which Mutation to apply. ... View more

Hi, I have made some typos when creating properties (types) and would like to remove the property types listed in the browser. Is there a command for that? Also, the schema has some relationships that are not in the graph, but appears in the graph schema. How to clean that up? I cannot seem to find solution for this documented anywhere - except starting all over again. br Kirsten ... View more

If I have a property with a long string, it would be nice if the Browser's property view box at the bottom of the cell was growable. (This is not an issue with Bloom, which has plenty of space to show a big property.) For example, I added a property "synopsis" to the movie DB. Since the string is very long, it won't entirely fit inside the bottom property viewer. The box is scrollable, so I can eventually see the entire property, but it's annoying to have to scroll all the time. ... View more

Somebody else had this problem. When I tried to downgrade to 4.1.4, the Downgrade button is dimmed. (I'm currently on 4.2.1.). The reason why I want to do this, is because Neosemantics only supports 4.0 and 4.1. (P.S. It would be nice if all Neo4J supported code could move forward when a new release is made.) At first, I thought maybe it's because I've been deleting old versions of the DB. So, I spun up a new DB with 4.1.4 but still the Downgrade button is dimmed for my old DB. I also tried upgrading my new DB to 4.2.1 and then trying to downgrade to 4.1.4 but for this new DB that I would have thought would "know" about 4.1.4 doesn't seem to. Again, I can't Downgrade to a previous version. See also: How to downgrade neo4j Newbie Questions Downgrading you can do in the Neo4J desktop program, stop the database. Click on the 3dots and select manage; select the upgrade tab and select the correct version. Alternatively you might want to create a new database with a recent 3.x version and use that for your application. [image] ... View more

As a Neo4j Bloom user, I want to be able to disable edge labels and / or change their color to maximize visibility and improve rendering so that I can see the graph query results better and prevent the edge labels from causing too much visual clutter. Acceptance Criteria: Users should be able to toggle the visibility of specific edge labels on or off. Users should be able to change the color of edge labels. Ideally, the user should be able to enable a "Match edge color" option so that the edge label matches the current color of the edge itself (convenient when utilizing conditional formatting). ...

As a user attempting to display fairly long text (5 - 15 words) in certain nodes within Neo4j Bloom, I want to be able to resize the text within the node so that I can see a decent portion of the article text as the caption. Currently, even at the "4x" node size the text is much too large to render even 50% of the text that I am attempting to display. Acceptance Criteria: Users should be able to override text size for nodes. By reducing text size, nodes at 4x size should be able to render ~10-15 words before cutting off the text with an ellipsis. ... View more

Hey, Is there a way to submit a mistake in a documentation to neo4j?

As a potential new course in the Graph Academy, would it be possible to have a segment on how to handle Super Nodes in Neo4j? The article by @david.allen clearly explains how to handle this problem, but it would be even better to have a hands-on tutorial that users can solve so that they can better understand the causes of Super Nodes and how to solve these issues.
