similar to: Migrations and doubles?

Hi... I want to know the equivalent instructions to insert, update, search and delete a registry. I know Rails can do it easily Thanks to ActiveRecord, but here''s the catch: I''m using PostgreSQL. As I''m using SQL to do the migration (Including the foreign keys), I need to know if I can use SQL queries to do those actions. Is there an example out there? I uncommented

Hi- I am trying to find a way to diffuse GIS data on a European map. I have a dataset consisting of particular locations scattered across Europe, along with magnitude and value information. I can plot these as discrete points with something like the following: "geocode" is a dataframe with four columns: LAT; LONG; MAGNITUDE;VALUE. library(maps) library(mapdata)

Hi all, This is my first post to the forum, and I''ll point out right away that I''m a noob to everything, Ruby, Rails, MySQL, etc., so I expect that I''m wrong here, but is the ''year'' datatype missing from ActiveRecord in 2.0.2? According to my MySQL 5.0 reference manual, ''year'' is a datatype, but when I try to run a migration that has

Hola. Tengo algún tipo de problema con las tildes, a la hora de trabajar en R o en RStudio, que no sé resolver. Intentando reproducir en dos PCs distintos, ambos con Windows 7, uno de los últimos ejercicios que ha publicado Carlos Gil Bellosta en su blog ( https://www.datanalytics.com/2016/06/20/6602-767-km-alrededor-de-espana-para-visitar-todas-sus-capitales-de-provincia/), me ocurre que al

Hola, Carlos. Pues, efectivamente, me ha ayudado. Sobre la utilización de la función geocode con ciudades con tilde, me dio Carlos Gil Bellosta anteriormente la idea de utilizar iconv para transformar la cadena de búsqueda a UTF-8, y yo lo utilicé para intentar transformar el output de html_table sin resultado: capitales <- read_html("

Hola, Carlos. A mí también me resulta raro, porque no me pasa siempre. Es un poco aleatorio. Imagino que habrá alguna razón, y que el código de la página estará relacionado, claro, pero no consigo averiguar a qué se debe. Además las pruebas que hago me dejan todavía más perplejo. Esto Encoding(capitales) me dice que el encoding es "unknow", pero luego esto validUTF8(capitales) me

Hello, A very simple question but I am stuck. I have an excel file each row is an address. However, I cannot make geocode read each line and come up with the latitude longitude. Could you please correct my code? library(ggmap) X<-c (2 Afxentiou Ampelokipi Thessaloniki Greece, 2 Afxentiou Ampelokipi Thessaloniki Greece, 4 Afxentiou Ampelokipi Thessaloniki Greece, 55 Agathonos

Estimados Sobre como obtener la geolocalización, aparte de lo aportado por Rubén Casal, también existe el api de Microsoft, lo que yo descartaría es tomar una base de datos con geolocalización, teóricamente andarían pero si uno por casualidad conoce la geografía real, se da cuenta de errores, salvo que en España los datos estén correctos.

hello.. i am currently trying to use :through to attach two of my models together using geokit. for some reason, i am running into a problem: ArgumentError: Unknown key(s): as i have two models, one that is geocoded, and one that belongs to that model. the models look like: ,----[ employer.rb ] | class Employer < ActiveRecord::Base | acts_as_mappable | before_validation_on_create

I started my app before migrations were a best practice and have been using SQL scripts. Now I''m looking at potentially having to move from using MySQL to postgreSQL to use a particular hosting provider. I understand migrations are the way to go to make this ''easy'' but it also looks like the use of migrations introduces extra work in other areas. I''d really

I am thinking that I have found a bug in Rails migrations. My app is using UUIDtools to generate guids for primary keys. To do this I pass :id=>false and then create my own id column as shown below. Next I leverage "execute" to create an index. It seems to work fine. The table in MySql is perfect. However the ID column and primary key on the ID column are not in the schema.rb file I

This is my first time working with REST and XML. My goal is to access Google''s geocoding service using HTTP. Here''s the code I have so far: require ''open-uri'' require ''rexml/document'' include REXML url=''http://maps.google.com/maps/geo?'' address = ''q=1600 Amphitheatre Parkway Mountin View,CA'' address1 =

Hi, I was trying to use the geocoding stuff in Mapstraction and found a bug with IE6. I couldn''t find a way of submitting it on Trac, so here it is. Change line 110 of mapstraction-geocode.js from: place = response.Placemark[0]; to: var place = response.Placemark[0]; Otherwise IE6 doesn''t declare the variable properly and things break in obscure ways. Cheers, Tom

This is a stupid question I know, but it is driving me crazy - I am missing something simple and basic here. I am trying to update missing zip codes on a data table. I am doing something incorrectly as the data in the Source table is not being updated, only the value in the array is changed. How do I get this to update the actual DB record instead? def add_missing_zips #find all records in

I''m currently planning a social app in Rails that relies on being able to see how far you are from everyone else. It''s my intention to store rough geo-coordinates as part of the sign up process. My intention is to capture their zipcode or postal code, and then be able to query a webservice once for that data. It''s also possible that there might be a database or even

Buena tarde a todos, Estos realizando un proceso que requiere asignar coordenadas a un buen número de registros. Estoy usando el paquete ggmap, pero luego de hacer uso de la georeferenciación se genera el error "geocode failed with status OVER_QUERY_LIMIT" debido al límite de registros diarios. A pesar de decir el error que es cada día, ya me está generando error con pocos registros

I''m new to Rails3, and I''m just trying to get one last thing to work before I call it a night. The situation is the following (please if the code is horrible, just let me know, still learning): I want to log a dive. I might have a new location on that dive at which point I have to create a new Location, and then create the dive. A dive has_one location. A location has_many
